Electric portion 73 can improve the radiance of antenna.Second current feed department 73 can preferably in the second gap 80 with two on the face X-Z
Metal covering forms coupling surface.That is, the second current feed department 73 can be arranged preferably with the screen vertical of mobile communication terminal.
As shown in fig. 6, the opening mode in first gap 50 in the second gap 80 and first embodiment of second embodiment is not
Together.Second gap 80 of second embodiment is open along the direction parallel with screen.
As described above, side metal edge frame 30 can have certain width, side metal edge frame when watching from Z-direction
30 a part can extend internally, that is, side metal edge frame 30 may include each extending over as in face of the front side of mobile communication terminal
With the extension metal edge frame of rear side, the second gap 80, which can be symmetrically formed at, to be extended in metal edge frame, and the second current feed department 73 can
To be mounted in the second gap 80, the second current feed department 73 can be arranged preferably with the screen vertical of mobile communication terminal.
Extending metal edge frame can be covered by the rear cover of the screen of mobile communication terminal or mobile communication terminal, this
In the case of, extend a part that metal edge frame can also be considered as metallic support or metal body mentioned above.In other words, symmetrically
Ground is formed in two gaps extended in metal edge frame and is covered respectively by the screen of mobile communication terminal and rear cover, therefore can change
Kind appearance.At this point, rear cover is preferably made of nonmetallic materials (for example, plastics or ceramics).
Second current feed department 73 can pass through the second gap 80 and be plugged in metal body.For example, the second current feed department 73 can be with
It is plugged in the metal edge frame of mobile communication terminal along the second gap 80 is passed through with the direction of screen vertical.
For example, the second current feed department 73 can be removably mounted in the second gap 80.In addition, the second current feed department 73 can be with
It is mounted in the second gap 80 by corresponding bracket (for example, plastic stent), and mainboard can also be attached directly to and keep solid
It is fixed.
Preferably, the Anneta module of second embodiment according to the present invention may also include loading plate (for example, unshowned print
Printed circuit board), the second current feed department 73 can be arranged on loading plate, and be arranged in the second gap 80 together with loading plate.
As described above, loading plate can be the non-metal board made of nonmetallic materials, however, the invention is not limited thereto, loading plate can
It is made of the material of any material, as long as loading plate does not have electric conductivity and electromagnetic wave shielding.
Loading plate can be and the mutually independent plate of the mainboard of mobile communication terminal, that is to say, that loading plate can be preparatory
It is formed as one, is removably mounted in the second gap 80 with the second current feed department and the second electrical connection section etc..
Preferably, the Anneta module of second embodiment according to the present invention may also include Jie being filled in the second gap 80
Electric portion 60 (for example, resin), the second current feed department 73 can be set in dielectric section 60, as shown in Figure 7.
Dielectric section 60 can be formed in the second gap 80 by injection molding, and dielectric section 60 can be used as support portion, for example, being situated between
Electric portion 60 may be used as the support portion of loading plate, in the case where no loading plate, dielectric section 60 also be used as current feed department or
The support portion of electrical connection section.
In addition, dielectric section 60 there can be predetermined dielectric constant, the resonance frequency of radiofrequency signal thus can be influenced.Tune can be passed through
The dielectric constant of dielectric section 60 is saved to design different gap sizes.That is, can be normal by the way that the dielectric of dielectric section 60 is arranged
Several and gap size (for example, the length in gap) transmits resonance signal.
Similar with first embodiment, second embodiment according to the present invention Anneta module may also comprise impedance matching circuit,
The impedance matching circuit can be such that the impedance of transmission line matches with the impedance of antenna holding to prevent stop signal reflection, such as make gap
The impedance holding of the transmission line of the impedance and radiofrequency signal of current feed department under environment matches.Although being not shown in the drawings, resistance
Anti- match circuit can connect between electrical connection section (for example, thimble) and transmission line, and can be realized by lc circuit.
Therefore, when Anneta module works, current direction are as follows: when Anneta module is as transmitting antenna module, electric current is from master
Radio circuit on plate passes through impedance matching circuit via transmission line, is then transferred to the second current feed department using thimble, via
Energy is coupled in the second gap 80 by the second current feed department, and resonance forms electromagnetic field radiation and goes out at the second gap 80.The same day
It is opposite when current direction is with transmitting when wire module is as receiving antenna module.
In addition, when seated, it can be by the second current feed department 73 (or by second current feed department 73 and dielectric section 60 as one)
From the second gap 80 that the front side of mobile communication terminal or rear side insertion extend metal edge frame, one end of thimble can be located at
Second gap, 80 inside is simultaneously electrically connected with the second current feed department 73, and the other end can be electrically connected with impedance matching circuit.
Fig. 8 is the radiation direction for showing the section XZ of the Anneta module of mobile communication terminal of the second embodiment of the present invention
Figure, Fig. 9 is the antenna pattern for showing the section XY of the Anneta module of mobile communication terminal of the second embodiment of the present invention.
The opening in the second gap 80 is along Z-direction, so electromagnetic wave main lobe direction is along+Z and -Z direction.
It can be seen that the main energetic of Anneta module toward screen and rear cover both direction from the antenna pattern of Fig. 8 and Fig. 9
(+Z and -Z direction) radiation, the energy very little on X/Y plane, so the mainboard and metallic support that are located on X/Y plane are to antenna
Radiance influences very little, and there is no need to reserve specific empty regions in the region.
According to an embodiment of the invention, opening up gap in metal edge frame, the coupling of current feed department and gap is believed via radio frequency
Resonance number at gap realizes energy transmission.
According to an embodiment of the invention, gap can be formed at least one metal edge frame of mobile communication terminal, thus
New antenna area can be opened up.
The Anneta module of embodiment according to the present invention is convenient for batch production and quickly and easily installs.
The foregoing is merely the preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, any
The change or replacement that those familiar with the art is readily apparent that in the technical scope disclosed by the present invention, should all cover
Within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
