Abstract
The utility model relates to a cell phone antenna and especially relates to a cell phone antenna equipped with an auxiliary parasitic antenna. The utility model provides the cell phone antenna equipped with an auxiliary parasitic antenna, and the cell phone antenna comprises a support. The support is provided with a main antenna and an auxiliary parasitic antenna, wherein the auxiliary parasitic antenna and the main antenna are coupled to each other. The beneficial effects of the cell phone antenna are that the auxiliary parasitic antenna is additionally arranged and is coupled to the main antenna, so that bindwidth is increased.
Description
Technical field
The utility model relates to antenna for mobile phone, relates in particular to a kind of antenna for mobile phone with auxiliary passive antenna.
Background technology
The radiofrequency signal power of radio transmitter output is transported to the antenna mobile phone antenna through feeder line (cable), is radiate with the electromagnetic wave form by antenna.After electromagnetic wave arrives and receives the place, next (only receive very little a part of power), and deliver to radio receiver through feeder line by antenna.It is thus clear that antenna is to transmit and receive an electromagnetic important wireless device, does not have antenna also just not have radio communication.Antenna is various in style, and for using under the different situations such as different frequency, different purposes, different occasion, demands of different, antenna for mobile phone then is mainly used in the mobile phone.
Existing mobile phone is in order to improve the aesthetic feeling of moulding aspect; Usually can antenna be built in the mobile phone, i.e. built-in aerial, but because a large amount of electronic devices also need be installed in mobile phone inside; Cause its inner space not enough, built-in aerial receives the constraint in space the defective of insufficient bandwidth will occur.
Summary of the invention
In order to solve the problems of the prior art, the utility model provides a kind of antenna for mobile phone with auxiliary passive antenna.
The utility model provides a kind of antenna for mobile phone with auxiliary passive antenna, comprises support, and said support is provided with main antenna and auxiliary passive antenna, and said auxiliary passive antenna and said main antenna are coupled.
As the further improvement of the utility model, said auxiliary passive antenna and said main antenna high-frequency coupling.
As the further improvement of the utility model, said auxiliary passive antenna ground connection.
As the further improvement of the utility model, said main antenna is the GSM antenna.
The beneficial effect of the utility model is: through such scheme, increase auxiliary passive antenna, and be coupled through auxiliary passive antenna and main antenna, increase bandwidth.
Description of drawings
Fig. 1 is a kind of structural representation with antenna for mobile phone of auxiliary passive antenna of the utility model.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further specified.
Drawing reference numeral among Fig. 1 is: support 1; Main antenna 2; Auxiliary passive antenna 3.
As shown in Figure 1, a kind of antenna for mobile phone with auxiliary passive antenna comprises support 1, and said support 1 is provided with main antenna 2 and auxiliary passive antenna 3, and said auxiliary passive antenna 3 is coupled with said main antenna 2.
As shown in Figure 1, said auxiliary passive antenna 3 and said main antenna 2 high-frequency coupling.
As shown in Figure 1, said auxiliary passive antenna 3 ground connection.
As shown in Figure 1, said main antenna 2 is the GSM antenna.
A kind of antenna for mobile phone with auxiliary passive antenna that the utility model provides is mainly used in bar phone or the slide phone, is usually used in the above frequently multiband aerial of four frequencies or four; Near main antenna 2 next doors, add the auxiliary passive antenna 3 of a ground connection, through the high-frequency coupling between auxiliary passive antenna 3 and the main antenna 2; Make that the multifrequency bandwidth of main antenna 2 is wideer, voltage standing wave ratio is littler, and the reflection of antenna is also just littler; According to the electromagnetic field radiation principle, the power of complete machine can be stronger, can expand the bandwidth of main antenna 2; The Antenna Design that is used for multiband; Can let the simultaneously good realization of performance of a plurality of frequency ranges, save large stretch of antenna space, more help the appearance design of complete machine.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection range of the utility model.
