The present invention relates to be used in that the medium substrate surface forms emission electrode with the electrical length of 1/2 wavelength in the frequency band of receiving and transmitting signal and with the panel type antenna mounted on surface and the installation method thereof of board-like work.In more detail, the structure that the present invention relates to when installation base plate upper mounting plate formula antenna, do not adopt the feed core to connect installation base plate, connect at the installation base plate back side, but only also can connect the panel type antenna mounted on surface and the installation method thereof of feed core by the installation base plate surface.
Background technology
The structure of Patcho antenna, as the example among Figure 10 A and the 10B, on a surface of medium substrate 21, constitute the shape of antenna emission electrode 22 by conducting film, be similar to is that (λ is the wavelength of transmitting-receiving frequency band to λ/(2 ε r1/2) on one side, ε r is the dielectric constant of medium substrate) square (aspect ratio to the gain, characteristics such as frequency bandwidth are influential), at center from antenna emission electrode 22, distributing point 22a is set the position of displacement separately at x direction of principal axis and y direction of principal axis, feed core 23 is connected with its distributing point 22a, and the other end of its feed core 23 is connected with feed circuit.
In the Patcho antenna, the central part of antenna emission electrode 22 becomes the maximum point of electric current, in end electric current minimum, promptly also, owing to form voltage be maximum distribution, from central division, all to have the impedance of supply side be impedance about 50 Ω in the position of displacement x direction of principal axis and y direction of principal axis two sides, at this part formation distributing point 22a, again, at the conducting film of the back side of medium substrate 21 formation as grounding electrode 25.Again, feed core 23, via the through hole 25a of the through hole 21a of medium substrate 21 and grounding electrode 25, separate, stretch out to downside with grounding electrode 25.
On the other hand, as the pattern of carrying out mounted on surface with Patcho antenna, for example also can adopt formation such shown in Figure 11 A and 11B: the feed line 43 of the Patcho antenna that linearly polarized wave is used is drawn, is formed current feed department 44 at its back side to the back side of medium substrate 41 via the side of medium substrate 41 from the sidewall of emission electrode 42, directly goes up tin with backflow (リ Off ロ one) stove etc. on installation base plate etc.(can with reference to such as Japanese Patent Application Publication communique 2002-314325 number)

Concrete execution mode
Below, with reference to accompanying drawing, panel type antenna mounted on surface of the present invention is described.That show among Figure 1A and Figure 1B is the 1st embodiment.On the surface as the one side of medium substrate 1 emission electrode 2 being set, is being that the back side is provided with grounding electrode 5 as the face with the one side subtend of medium substrate 1.In addition, an end 3a of feed core 3 is connected with emission electrode 2, and he end 3b stretches out to rear side via the through hole 1a that is arranged at medium substrate 1.Can form such structure: in the rear side of the medium substrate 1 of this through hole 1a, formation and through hole 1a almost concentric and have in all diameters recess 1b bigger than the diameter of through hole 1a, simultaneously, his end 3b of feed core 3 almost is in same plane with the face that exposes of the grounding electrode 5 at the back side that is arranged on medium substrate 1, forms the structure that can directly carry out mounted on surface on the installation base plate surface.
The size of medium substrate 1, can be with emission electrode 2 described later big or small identical, but it is more bigger than emission electrode 2 usually, for example, using the dielectric constant of 1.575GHz, medium substrate 1 is 20 o'clock, the size of emission electrode 2 is the square of the 21m length of side, and the big I of medium substrate 1 makes the square of the length of side about 25mm.In addition, at the regulation position of medium substrate 1, form the through hole 1a that makes feed core 3 perforation usefulness described later.This through hole 1a connects feed core 3 described later, so can form such as about φ 1.2mm.In the present embodiment,, can form that almost concentric, diameter are about φ 3.5mm, the degree of depth is the recess 1b about 1.5mm with through hole 1a in the rear side of medium substrate 1.
This recess 1b is used to make when tin etc. is connected with installation base plate on the feed core 3 described later, guarantee to make the electroconductive member of tin etc. to be firmly fixed at the space of feed core 3, simultaneously avoid contacting with grounding electrode 5, so it is circular that section needn't be done, but insulated part can be removed into required Min. when circular.In addition, be electrically connected and there is no need to form recess 1b on time without the operation such as tin that goes up described later.
This emission electrode 2, as circularly polarized wave usefulness, thus form the square that the length L of horizontal stroke (x direction) and vertical (y direction) all has the electrical length of about 1/2 wavelength, but be not that non-square can not.As previously mentioned, the dielectric constant of medium substrate 1 is big more, and then its physical length L on one side can be done more for a short time, when the frequency of aforesaid receiving and transmitting signal is 1.575GHz, if employing DIELECTRIC CONSTANT r is 20 medium substrate 1, its length L on one side can be made about 21mm.On this emission electrode 2, x direction and y direction all some assigned position that departs from its central part C current feed department 2a is set, form the through hole that inserts feed core 3 usefulness described later at its current feed department 2a.But, do not form through hole, be connected, be provided with feed core 3 with the back side of emission electrode 2 and be fine yet.This current feed department 2a is formed on the position with characteristic impedance (for example 50 Ω) impedance for matching of the circuit side that is connected current feed department, and this current feed department 2a is arranged on the position that some departs from its central part C.
In the present embodiment, in the through hole that is arranged at this current feed department 2a, utilize scolding tin 6 etc. to make an end 3a of feed core 3 connect set.Feed core 3 can adopt the wire rod such as the formations such as brass of φ 1.2mm left and right sides thickness, and other ends 3b is arranged to almost become same plane with the face (following) that exposes of grounding electrode 5.The result is, is coated with paste soldering material etc. in advance in the part of the feed core 3 of connection substrate etc., with this Patcho antenna mounting on installation base plate etc., as long as utilize reflow ovens etc. feed core 3 can be electrically connected set with installation base plate.In addition,, form recess 1b as described above in the rear side of medium substrate 1, therefore, tin is bonded on the feed core 3, forms the soldering pin easily, and, can prevent to contact with grounding electrode 5.
In the present embodiment, his end 3b side of feed core, the thickness of feed core 3 is constant, but as shown in Figure 2, form flange (plate part that diameter is bigger than feed core 3) 3c by his end side at feed core 3, can be connected with installation base plate more reliably, shown in Fig. 3 A～3C, can adopt the assembly 9 that earlier feed core 3 is connected medium substrate that the Patcho antenna that is bonded to installation base plate 7, then the electrode part of medium substrate 1 and emission electrode 2 or grounding electrode 5 is assembled uses and electrode part to embed assembling, make the installation method of the part insertion feed core 3 of its through hole 1a.Like this, after confirming reliable connection of feed core 3 and installation base plate 7, assembly 9 is covered, thus can make with feed core 3 be connected and with grounding electrode 5 discontiguous reliabilities raisings.In addition, the internal diameter of Ci Shi recess 1b also with aforesaid the same, be φ 3.5mm.The diameter of flange 1c is about φ 2.5mm.
Promptly also, at first, such as shown in Figure 3A, the assembly 9 that the structure shown in formation and Figure 1A and the 1B is same.At last, shown in Fig. 3 B like that, at the position of the feed core of connection substrate 7 feed core 3 erected, and connect sets with scolding tin 8.At this moment, his end side at feed core 3 forms flange 3c, so, can put well on the installation base plate 7 like this and carry out with reflow ovens etc. on tin, can not only go up tin very simply, and can confirm on it tin state and can or can not extending transverselyly too much cause contacting with grounding electrode 5.After this, shown in Fig. 3 C,, on installation base plate 7, can directly carry Patcho antenna by aforesaid assembly 9 being covered and utilizing scolding tin 6 to make the leading section 3a of feed core 3 be connected set with emission electrode 2.
According to installation method shown in Figure 3, will be showed in Fig. 6 to the VSWR of the Patcho antenna under the state that is installed on installation base plate and the result of study of emission characteristics; Among～the 7B.In the present embodiment, not only form through hole 1a on the medium substrate 1, also form recess 1b in its rear side, as shown in Figure 6,1.575GHz the VSWR value of locating is about 1.56, relatively, almost has only the difference of measure error degree with about 1.52 of structure in the past, in addition, aspect emission characteristics, full mean value (the full mean values that each emission angle of two directions that are perpendicular to one another shown in Fig. 7 A described later and the 7B is 360 °), full mean value in the structure in the past is-0.59dBi, is-0.72dBi to obtain almost unconverted emission characteristics in the present embodiment.
What Fig. 7 A showed is, as shown in Figure 8, with the face side of the emission electrode 2 of antenna as the z axle, with respect to the center C of emission electrode 2, distributing point 2a as shown in Figure 8, emission characteristics in the z-x face when setting x axle, y axle, Fig. 7 B shows is emission characteristics in the y-z face of its vertical direction.The mean value of the emission characteristics shown in Fig. 7 A is-0.85dBi, and the mean value of the emission characteristics shown in Fig. 7 B is-0.59dBi, with separately in the past value-the 0.73dBi in the structure ,-0.45dBi relatively, though low, not a halfpenny the worse.
On the other hand, in order to be surface mounted in the medium substrate back side 1 result of study of recess 1b to the influence of antenna performance generation is set, the variation of VSWR when as shown in Figure 9, making the size generation many variations of recess 1b among the 1.575GHz, be about 10mm with influence interior, that can confirm to be subjected to hardly recess 1b in the size diameter of recess 1b.Here the size of so-called recess 1b, the diameter when referring to as section to circular recess, the size of medium substrate 1 and thickness are the size of previous example, concave depth is 1.5mm.
That is, even carry out mounted on surface, also can guarantee the space that soldering is used, feed core 3 can be connected on the installation base plate very reliably, and, feed core 3 and grounding electrode 5 are short-circuited.In addition, emission characteristics also has same tendency with respect to the influence of the size of recess 1b.
Like this, the substrate back side of the through hole 1a that connects by the feed core of making at medium substrate 13 is provided with recess 1b, make his end 3b of feed core become almost conplane structure, just can his end 3b side of feed core 3 be directly connected to the installation base plate surface by last tin etc. with the face that exposes by ground electrode 5.Promptly also, do not have flange at he end 3b of feed core 3, as before with thin feed core 3, therefore, can use the solid of a little scolding tin etc. to connect set on every side because of around feed core 3, there being the space that forms by recess 1b, in his end side of feed core 3 more.Its result, even feed core 3 connected in the through hole of installation base plate and carry out soldering etc. in the installation base plate rear side, also Patcho antenna can be placed on behind the installation base plate surface some of semi-finished product side by side, and only install simultaneously by reflow ovens etc., installation effectiveness is improved greatly.
Again, because his end side at feed core 3 forms flange 1c, need with the expanded in size of recess 1b some, as previously mentioned, characteristic does not almost have influence in the time of in the diameter of recess 1b about 10mm, such flange 1c is set the reliability of following with installation base plate is further improved.
The Patcho antenna of in Fig. 4 A and 4B, showing relevant the 2nd embodiment of the present invention.According to present embodiment, he end 3b of feed core 3 can make the movable core that can utilize the outstanding length of change such as spring, and its he end 3b can be provided with to such an extent that give prominence to than the face that exposes of grounding electrode 5.Thereby can obtain such structure: but on installation base plate fixedly the time, can push up by the power of his end of feed core 3 on the installation base plate, keep with situation that the installation base plate surface electrical contact under shrink, be able in the surperficial enforcement of installation base plate mounted on surface.In other words, this is not to utilize the solid of scolding tin etc. to connect, but the example that utilizes the roof pressure contact to connect.The result is, do not need to deposit the space of binding agents such as leg, shown in Fig. 4 A, do not need recess in the rear side of medium substrate 1, and an end 3a of feed core 3 only utilizes emission electrode 2 and wlding 6 etc. to be connected and fixed, and he is free state at end 3b side.
Like this, because his end 3b side of feed core 3 is made movable structure, so but can be connected with the current feed terminal of installation base plate by its power, there is not recess can contact reliably yet.Again, spring does not adopt coil spring such shown in Fig. 4 B good, and all rubber-like members such as flat spring are also all available, and the means that movable core is not pulled out from metal tube 31 also are diversified.
As feed core 3, when using so movable core, as described later variation like that, need make the connection device of Patcho antenna roof pressure to the surface of installation base plate, but because the elastic force of this spring is little, so, be fixed in installation base plate as Patcho antenna that will be in the past, adopt the two sides jointing tape to fix, or all be desirable by the method that is fixed in installation base plate at grounding electrode portion scolding tin etc.
Fig. 5 A～5E is last, and what show is the variation of the 2nd embodiment.In the present embodiment, constitute feed core 3 with movable core, and thereunder form flange 34, simultaneously, form recess 1b in the rear side of the through hole 1a of medium substrate 1.As previously mentioned, be below the φ 10mm if concave depth is 1.5mm, diameter, then its emission characteristics almost there is not influence, so the space as form flange 34 in the periphery of feed core 3 can form recess 1b.The result is and since when inserting feed core 3 flange 34 run into recess the end, utilize wlding 6 etc. that one end 3a and emission electrode 2 are connected and fixed, can make the correct position ground secured in alignment of feed core 3, operating efficiency is improved greatly.
In the concrete example, at first, shown in Fig. 5 A like that, same with the 1st embodiment, in the position of regulation, respectively form on the surface of the medium substrate 1 that forms through hole 1a and recess 1b emission electrode 2, form grounding electrode 5 overleaf, and form assembly 9.After this, shown in Fig. 5 B, like that, will there be an end 3a side of the feed core 3 of flange 34 to insert in the through hole 1a with the same movable core 33 of Fig. 4 B with in its periphery from the rear side of medium substrate 1.At this moment, when insertion makes the end that flange 34 meets recess 1b, leading section 3a just is near the surface of emission electrode 2.Then, shown in Fig. 5 C, like that, utilize wlding 6 grades that the one end 3a and the emission electrode 2 of feed core 3 are connected and fixed.At this moment, in state following time of be coated with solder(ing) paste in advance at the connecting portion of emission electrode 2, medium substrate 1 upside-down mounting, the feed core 3 that will have movable core 33 and a flange 34 being inserted the end of meeting recess 1b in the through hole 1a, at flange 34, will many be carried out set, formation Patcho antenna 10 by reflow ovens etc. quickly simply.
On the other hand, like that, the place at the installation Patcho antenna of installation base plate 7 installs and fixes the fixer 35 that board-like antenna is used in advance shown in Fig. 5 D.This fixer 35 for example utilizes the resilient resin etc. and the size of Patcho antenna to form accordingly, forms and Patcho antenna 10 can be fixed on the regulation position that its feed core 3 is connected with the current feed terminal of installation base plate 7.But, even so special fixer is not set, so long as to utilize the fixing means belong to Patcho antenna in the past be the such bonding agent of two sides adhesive tape, utilize conductivity solid that welding etc. fixes grounding electrode etc., can fix getting final product with the power that stands spring force.And, shown in Fig. 5 E like that, utilize fixedly Patcho antenna 10 of fixer 35, can make the feed core can be connected lift-launch with the current feed department of installation base plate 7.In addition, even grounding electrode 5 is directly followed without the grounding parts of electroconductive member and installation base plate 7, get final product so long as high frequency connects, as previously mentioned, available common two sides jointing tape is bonding.
By making feed core with so movable core, the rear side that not be used in medium substrate is provided with recess and the feed core can be connected to the installation base plate surface, medium substrate adopts under the situation of structure same, also Patcho antenna can be carried out mounted on surface on installation base plate.In addition, owing to also can install, can adopt very simple operation that Patcho antenna is installed on the installation base plate without soldering etc.In addition, form recess by the back side at medium substrate, the feed core that will have movable core is made flanged shape, and it is very simple that the operation that the feed core is connected with emission electrode becomes, and can obtain having the antenna of certain mass simply.
