Mobile communication terminal and its antenna

Abstract

The invention discloses a mobile communication terminal and its antenna, which utilizes a baseband chip to control switches in which an additional wiring area is connected to a wiring area provided with feed points according to the working frequency range currently required by the antenna, so as to respectively realize communication in different frequency bands, The problem of mutual interference between the dual antennas in the prior art is avoided, and the space required for setting up additional antennas is saved, that is, the antenna occupation is reduced without affecting the performance of the antenna due to mutual interference. terminal space. Moreover, when the antenna is working, all effective antenna traces are used to realize signal transmission and reception in the same frequency range, which can have higher performance than conventional antennas, wider bandwidth coverage, and higher radiation efficiency, which is conducive to the application of antennas Sufficient performance can still be maintained in harsh environments with many metal parts.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a mobile communication terminal and its antenna. Background technique [0002] In the existing design of antennas for mobile communication terminals, the antennas often need to be able to communicate in low-frequency bands, intermediate frequency bands, and high-frequency bands, and need to cover a wide frequency band bandwidth. Therefore, the antenna needs to occupy more mobile communication terminals. interior space. Especially in some schemes where dual antennas are used to achieve communication in different frequency bands, for example, one antenna works in the low frequency band and the other antenna works in the intermediate frequency band. If the antenna is designed to reduce the distance between the two antennas Increasing the distance between the two antennas due to mutual interference will cause the above-mentioned problem that the antennas occupy too much space ...

Problems solved by technology

[0002] In the existing design of antennas for mobile communication terminals, the antennas often need to be able to communicate in low-frequency bands, intermediate frequency bands, and high-frequency bands, and need to cover a wide frequency band bandwidth. Therefore, the antenna needs to occupy more mobile communication terminals. interior space

Especially in some schemes where dual antennas are used to achieve communication in different frequency bands, for example, one antenna works in the low frequency band and the other antenna works in the intermediate frequency band. If the antenna is designed to reduce the distance between the two antennas Increasing the distance between the two antennas due to mutual interference will cause the above-mentioned problem that the antennas occupy too much space in the mobile communication terminal, and if the distance between the two antennas is reduced in order to reduce the space occupied by the antennas in the mobile communication terminal, the problem will be Causes the mutual interference between the two antennas to increase, thus affecting the performance of the two antennas
