Below in conjunction with drawings and embodiments, the utility model is described in further detail.
As shown in Figure 1, the novel mobile communication equipment that a kind of metal shell is provided of this use, it comprises metal shell on the back 31, form the metal edge frame 32 of receiving space with metal shell on the back 31 and to be placed in receiving space and wiring board 33 spaced with metal shell on the back, and described mobile communication equipment is provided with an antenna assembly 10 further.
As shown in Figure 2 and Figure 3, for the antenna assembly 10 of mobile communication equipment, comprise Department of Radiation 101, the systematically unit 102 arranged with Department of Radiation 101 relative spacing, the earth point 103 extended respectively to systematically unit 102 direction by Department of Radiation 101 two ends and the feedback point 104 between earth point 103.In antenna assembly 10 of the present utility model, Department of Radiation 101 is made up of metal material, itself and systematically form resonant circuit between unit 102, thus form effective radiation space.Systematically unit 102 is provided with electrical connection feeder line 1021 thereon, and feeder line 1021 is electrically connected with feedback point 104, thus forms the signal transmission line of antenna assembly 10; Earth point 103 is electrically connected, for the resonance frequency of control antenna device 10 with systematically unit 102; In order in the overall volume not increasing antenna assembly 10, avoid single employing in present embodiment and increase the frequency range that Department of Radiation 101 and the distance of systematically unit 102 realize increasing antenna assembly 10, but regulate by least one being arranged in series a Dynamic Matching switch 105 in feedback 104 or earth point 103.Concrete, in present embodiment, feedback point 104 and earth point 103 are all arranged in series a Dynamic Matching switch 105, and dynamic tunable capacitor selected by Dynamic Matching switch 105.Certainly, in other execution modes selectable, also can only connect on feedback point 104 Dynamic Matching switch 105 or Dynamic Matching switch 105 of only connecting on earth point 103, all can implement.
For the problem that bandwidth is narrower, by the band bandwidth regulating the value of dynamic tunable capacitor directly to adjust antenna assembly 10.Ginseng Fig. 4, its principle is: f1, f2 and f3 are the resonance frequency curve of different bandwidth, and resonance frequency curve f2, by regulating dynamic tunable capacitor, widens to f1 and f3 by antenna assembly 10 of the present utility model, thus reaches the object increasing bandwidth.Concrete, the working band scope of antenna assembly 10 of the present utility model is: 698-960MHz, 1710-2690MHz.
It should be noted that, feedback point 104 and earth point 103 are arranged in series the value volume and range of product that adjustable coupling switch 105 is not limited to present embodiment, but its principle is all the same.
In present embodiment, in order to increase the radiating surface of antenna assembly 10 further, antenna assembly 10 also comprises lid and is located at systematically on the unit 102 and auxiliary radiation portion 106 of setting with interval.Department of Radiation 101 and auxiliary radiation portion 106 are all metal material and make.
In present embodiment, auxiliary radiation portion 106 is also provided with some tie points 1061, systematically unit 102 and auxiliary radiation portion 106 are formed by tie point 1061 and are electrically connected, and this structure effectively can reduce noise signal, thus improves radiation efficiency further.
More excellent, Department of Radiation 101 comprises radiating principal 1011 and is bent the radiation accessory body 1012 of extension by radiating principal 1011 two ends respectively, and radiation accessory body 1012 is arc.Radiating principal 1011 and systematically unit 102, just to setting, effectively can improve radiation efficiency.
For the utility model mobile communication equipment for mobile phone with metal shell is described further, join shown in Fig. 1: the PCB 33 that mobile phone (non-label) comprises metal shell on the back 31, jointly surrounds the metal edge frame 32 of receiving space (non-label) and be placed in described receiving space with metal shell on the back 31 simultaneously.When antenna assembly 10 is assembled in described mobile phone, namely metal edge frame 32 can be used as Department of Radiation 101 and uses, the sidepiece 322 that metal edge frame 32 comprises top body 321 and extends from the bending of top body two ends.
Top body 321 serves as radiating principal 1011, sidepiece 322 serves as radiation accessory body 1012, described both sides 322 are respectively equipped with the feeder line 1021 extended to wiring board direction, and described feeder line 1021 is electrically connected formation two earth point with systematically unit 102, and described feedback point 104 is between two earth points 103.Described feeder line 1021 can be independently wire, also can be the conducting wire be integrated in wiring board, in the present embodiment, for being integrated in the conducting wire in wiring board.
The arc of the radiation accessory body 1012 of Department of Radiation 101 is provided with the arc be beneficial in conjunction with mobile phone metal edge frame 32, increases cell phone appearance aesthetic feeling; Namely PCB 33 can be used as systematically unit 102 and uses; Namely mobile phone shell on the back 31 can be used as auxiliary radiation portion 106 and uses, and the direct inner side at mobile phone shell on the back 31 can be arranged some radiants 311 and use as tie point 1061, in order to itself and PCB 33 are connected to form radiation effect, increases band bandwidth.Thus without the need to carrying out the band bandwidth arranging and can reach and increase antenna assembly 10 that cracks on mobile phone shell on the back 31.Whole antenna assembly 10, when being used in mobile phone, sharing the section structural of its part metals part as antenna assembly 10 in conjunction with handset structure, further increases the radiation efficiency of antenna assembly 10.Further, mobile phone overall appearance aesthetic feeling is unaffected.
On the telecommunications products such as certainly, the utility model mobile communication equipment is not limited to be used on mobile phone, also can be used in wearable device, the panel computer that size is less, its principle is all the same.
Compared with correlation technique, the object increasing band bandwidth by regulating dynamic tunable capacitor to realize and improve radiation efficiency when the utility model mobile communication equipment can not increase its overall volume.And by the metal casing member of mobile communication product described in Appropriate application as the part-structure of antenna assembly 10, thus the object that can reach and increase band bandwidth and improve radiation efficiency that the shell realizing noting be used in described telecommunications product cracks, maintain the aesthetic appearance of described telecommunications product simultaneously.
