Please refer to Fig. 1, it is the schematic diagram of a radio communication device MS of the embodiment of the present invention.For ease of illustrating, radio communication device MS is a handheld mobile device, but is not limited thereto, and radio communication device MS can also be flat computer, notebook computer, personal digital assistant or any electronic installation with radio communication function.Radio communication device MS includes a metal outer frame FRM, a housing HUS and an antenna 10.Metal outer frame FRM forms a part of housing HUS, its perfect mouth or one-body molded around around radio communication device MS.Housing HUS is provided with a grounding parts GND (not being plotted in Fig. 1), is used to provide ground connection.Antenna 10 is used for transmitting/receiving wireless signal, to realize radio communication.
Specifically, please refer to Fig. 2, it is the structural representation of antenna 10.As shown in Figure 2, antenna 10 includes two major radiator 11, a 12 and feed side 13 and parasitic radiator 14.Radiant body 11 is used for the low-frequency signal components (the present embodiment is 699 ~ 960MHz) of resonance one radiofrequency signal RF_sig.Radiant body 12 be arranged at metal outer frame FRM around region in, be used for the high frequency component signal (the present embodiment is 1710 ~ 2700MHz) of resonant RF signal RF_sig.Feed side 13 is electrically connected between radiant body 12 and grounding parts GND, is used for feed-in radiofrequency signal RF_sig.Radiant body 11 and 12 interval one, apart from LG, under specific range LG, can make to produce coupling between radiant body 11 and 12, allows radiofrequency signal RF_sig be fed into radiant body 11 via radiant body 12 coupling, or is passed to radiant body 12 by radiant body 11 coupling.
Operationally, when radio communication device MS wireless signal emission, radiofrequency signal RF_sig is fed into feed side 13, the high frequency component signal of radiofrequency signal RF_sig is directly radiated in the air by radiant body 12, and low-frequency signal components is fed into radiant body 11 by radiant body 12 coupling simultaneously, and radiant body 11 is made to be able to radiate low signal component to aerial.Otherwise, when radio communication device MS receives wireless signal, radiant body 11 and 12 is respectively by low, the high frequency component signal of responding to radiofrequency signal RF_sig in the air, low-frequency signal components coupling is sent to radiant body 12 via coupling by radiant body 11, low, high frequency component signal is then sent to rear end radio frequency processing module by feed side 13, with actions such as further executive signal analysis and demodulation.Thus, antenna 10 can pass through low, the high frequency component signal of radiant body 11 and 12 difference transceiving radio frequency signal RF_sig simultaneously, to carry out radio communication.
