Abstract
The utility model discloses an internal antenna for mobile phone, which comprises bracket; and low-frequency radiator, high-frequency radiator and transmission line disposed on the bracket. Left end of the low-frequency radiator is in parallel connection with upper end of the high-frequency radiator via the transmission line; antenna input/output terminal is disposed on the transmission line; antenna short-circuit terminal is disposed beside the antenna input/output terminal; and elastic extending parts of the antenna body are disposed under the antenna input/output terminal and the antenna short-circuit terminal. With the combination structure of high-frequency radiator, low-frequency radiator and strip transmission line, the internal antenna of mobile phone can be made of widely available cheap material at low manufacture cost and easy fabrication.
Description
Technical field
The utility model relates to a kind of antenna, especially a kind of built-in antenna of mobile phone.
Background technology
Mobile phone obtains use more and more widely as the communication apparatus in modern times.And mobile phone develops to functional diversities, direction compact, attractive in appearance, and antenna for mobile phone also should agree with the outward appearance and the structure of mobile phone.Antenna for mobile phone manufacturing cost in the prior art is cheap inadequately, the installation more complicated.
The utility model content
Technical problem to be solved in the utility model provides a kind of built-in antenna of mobile phone, can agree with the outward appearance and the structure of mobile phone, and cheap for manufacturing cost, install simple.
For solving the problems of the technologies described above, a kind of built-in antenna of mobile phone of the utility model, comprise support, be located at low frequency radiation body, high frequency radiation body and transmission line on the support, the left end point of low frequency radiation body is in parallel with the upper extreme point of high frequency radiation body by transmission line, and transmission line is provided with antenna I/O end, the other antenna short circuit end that is provided with of antenna I/O end, antenna I/O end has the elastic extension body of antenna body, and the antenna short circuit end has the elastic extension body of antenna body.
Built-in antenna of mobile phone of the present utility model adopts low frequency radiation body and two kinds of difform metal micro-strip pasters of high frequency radiation body, being pasted on vinyon places on the metal ground plate, low frequency as antenna is in parallel mutually through one section transmission line with the high frequency radiation body, the reactance of the short-circuit line that forms with the short circuit metal section compensates mutually again, on two frequencies resonance taking place, makes the work of antenna two-band.The utility model constitutes combined shaped with high frequency radiation body, low frequency radiation body and bar shaped transmission line, makes the utility model can adopt cheap material manufacturing, so low cost of manufacture of the present utility model, material ranges is extensive, and installs simple.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the utility model built-in antenna of mobile phone structural front view;
Fig. 2 is the utility model built-in antenna of mobile phone structure left view;
Fig. 3 is the utility model built-in antenna of mobile phone structure front view;
Fig. 4 is the utility model built-in antenna of mobile phone stereogram.
Wherein, 1 is the GSM900MHz radiant body, and 2 is the DCS1800MHz radiant body, and 3 is the antenna short circuit end, and 4 is antenna I/O end, and 5 is transmission line, and 6 are the elastic extension body, and 7 are the elastic extension body.
Embodiment
The utility model proposes a kind of built-in antenna of mobile phone, be applicable to that mobile phone etc. needs the communication apparatus of antenna.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, built-in antenna of mobile phone of the present utility model comprises support, the low frequency GSM900MHz radiant body that on support, is provided with, high frequency DCS1800MHz radiant body and transmission line, the low frequency radiation body is shape 1 copper sheet, the high frequency radiation body is shape 2 copper sheets, the left end point of low frequency radiation body 1 is in parallel with the upper extreme point of high frequency radiation body 2 by transmission line 5, on transmission line 5, be provided with antenna I/O end 4, at the antenna I/O end 4 other antenna short circuit ends 3 that are provided with, antenna I/O end 4 forms the elastic extension body 7 of antenna body downwards, and antenna short circuit end 3 forms the elastic extension body 6 of antenna body downwards.
Built-in antenna of mobile phone of the present utility model is with low frequency radiation body 1 and 2 two kinds of difform metal micro-strip pasters of high frequency radiation body, being pasted on vinyon places on the metal ground plate, low frequency as antenna is in parallel mutually through one section transmission line with the high frequency radiation body, the reactance of the short-circuit line that forms with the short circuit metal section compensates mutually again, on two frequencies resonance taking place, makes the work of antenna two-band.The utility model makes built-in antenna of mobile phone of the present utility model can adopt cheap material (as: materials such as sheet brass, foreign copper-nickel alloy, polyethylene) to make with combined shaped, structure that high frequency radiation body, low frequency radiation body and bar shaped transmission line constitute.Low cost of manufacture of the present utility model, material ranges is extensive, and installs simple.
