Embodiment Construction

[0014] In order to facilitate the understanding of those skilled in the art, the structural principle of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings:

[0015] Such as figure 1 As shown, in Embodiment 1 of the present invention, on the PCB board 8 of the mobile phone of ground clearance (ground clearance) in advance, be provided with and receive the signal from transmitting station and radiate the sheet antenna radiator 7 of the signal from radio frequency module, radio frequency module 6 and other circuit modules 5, a matching circuit 4 for adjusting antenna impedance is arranged between the patch antenna radiator 7 and the radio frequency module 6. Chip antenna radiator 7 adopts a standardized one-piece monopole radiator whose shape and wiring do not need further design. The chip radiator is made of phosphor bronze, stainless steel and other commonly used antenna shrapnel materials, and its...

Abstract

The present invention discloses an antenna device which is used for the double-frequency mobile phone and comprises a sheet antenna radiant body that receives the signal from the transmitting station and radiates the signal from the radio frequency module, the sheet antenna radiant body is coupled with a matching circuit used for adjusting the magnitude of the antenna impedance, the matching circuit comprises an aerial signal feed-in connecting point, a mobile phone signal feed-in connecting point and a pi-type network composed by the matching elements, the aerial signal feed-in connecting point is coupled to the antenna radiating unit, the mobile phone signal feed-in connecting point is coupled with the radio frequency module, and the pi-type network is coupled between the aerial signal feed-in connecting point and the mobile phone signal feed-in connecting point. The invention has the advantages of increasing the developing velocity of the mobile phone antenna, reducing the developing degree of the mobile phone antenna, shortening the period of developing and producing the mobile phone antenna and increasing the normalization and finished-production of the antenna designing.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an antenna for a dual-frequency mobile phone. Background technique [0002] At present, in the research and development and design process of ordinary dual-frequency monopole mobile phone antennas, the general design idea is to customize mobile phone antennas according to the different electromagnetic environments inside and outside the mobile phone, combined with the actual situation of the frequency band and indicators required by customers, because The functional requirements and performance index requirements of various mobile phone antennas have little difference. This customized design method often brings a lot of waste of design time and funds. However, if the customized design method is not adopted, the electromagnetic interference of mobile phones cannot be avoided The variability and complexity of the environment. [0003] China Patent No. ZL 200510108164.7 discl...
