Problems solved by technology

[0002] For current communication devices in the prior art, the antenna design method is to arrange different antennas for high and low frequency band signals on the same surface or on the same side to save the occupied surface area of ​​the communication device. When , the correlation coefficients of different antennas for high and low frequency band signals will become quite high, so that the size and area of ​​the antenna circuit design is still quite large. Other design applications of portable communication devices are difficult to realize. In addition, the correlation coefficient of the antenna is high, which will also lead to the reduction of communication quality

Abstract

A portable communication apparatus includes a first antenna radiator, a second antenna radiator, a first feeding point, a second feeding point, and a matching circuit. The first antenna radiator is used for radiating a high-frequency band signal. The second antenna radiator is used for radiating a low-frequency band signal. The first feeding point is coupled to the first antenna radiator and is utilized for processing feed-in or feed-out of the signal of first antenna radiator. The second feeding point is coupled to the second antenna radiator and is utilized for processing feed-in or feed-out of the signal of second antenna radiator. The first feeding point is separate from the second feeding point. The matching circuit is coupled to the first and second feeding points, and used for impedance matching with the first antenna radiator and the second antenna radiator.

Description

technical field [0001] The present invention relates to a mechanism of a portable communication device, in particular to a portable communication device designed with a separate antenna. Background technique [0002] For the current communication devices in the prior art, the antenna design method is to arrange different antennas for high and low frequency band signals on the same surface or on the same side to save the occupied surface area of ​​the communication device. When , the correlation coefficient of different antennas for high and low frequency band signals will become quite high, so that the size and area of ​​the antenna circuit design is still quite large. Other designs and applications of portable communication devices are difficult to realize. In addition, the correlation coefficient of the antenna is high, which will also lead to a decrease in communication quality. Contents of the invention [0003] Therefore, an object of the present invention is to disc...
