Description
Technical field
The present invention relates to a kind of antenna, particularly relate to a kind of mobile phone with having amplitude modulation and the antenna of two kinds of function of radio receiver of frequency modulation and the reception method of this antenna.
Background technology
Be the living and studying that is convenient for people to, mobile phone is as the electronic product carried, and its integrated function is more and more, as is the broadcast listening program, some mobile phone is integrated two kinds of function of radio receiver of amplitude modulation and frequency modulation.Usually, the amplitude modulation function of radio receiver of these mobile phones is realized by an amplitude modulation antenna part and an amplitude modulation operating circuit, and the frequency modulation operating circuit realizes that by a frequency-modulated antenna portion and a frequency modulation operating circuit amplitude modulation antenna part and frequency-modulated antenna portion are arranged in the mobile phone independently of one another.
Yet above-mentioned mobile phone reception antenna is because amplitude modulation operating circuit and frequency modulation operating circuit adopt separately independently antenna part, thereby it is big to take the inner space of mobile phone, and the incompatibility mobile phone is easy to carry and the requirement of the increasing development trend of function.
Summary of the invention
The objective of the invention is to provide a kind of at above-mentioned the deficiencies in the prior art reduces the mobile phone reception antenna of the inner space that takies mobile phone and its reception method is provided.
For achieving the above object, mobile phone reception antenna provided by the present invention comprises that an amplitude modulation operating circuit, a frequency modulation operating circuit, a shared antenna part and switch switch, this diverter switch has a back contact, one first and selects contact and one second to select contact, this back contact is connected with shared antenna part, first selects contact to be connected with the amplitude modulation operating circuit, and second selects contact to be connected with the frequency modulation operating circuit; Common antenna portion switchably is connected with amplitude modulation operating circuit or frequency modulation operating circuit by diverter switch.
The reception method of mobile phone reception antenna provided by the present invention comprises:
(1) a shared antenna part is set in mobile phone;
(2) overall length dimension according to common antenna portion is provided with an amplitude modulation operating circuit and a frequency modulation operating circuit;
(3) switch switch with one and be connected with shared antenna part, and by selecting diverter switch to be connected amplitude modulation or the FM radio of realizing reception antenna with amplitude modulation operating circuit or frequency modulation operating circuit.
As mentioned above, common antenna of the present invention portion switchably is connected with amplitude modulation operating circuit or frequency modulation operating circuit by diverter switch, replaced independently the amplitude modulation antenna part and the frequency-modulated antenna portion separately of prior art, thereby the inner space that can reduce mobile phone takies.
