Problems solved by technology

[0003] On the other hand, when using antennas for wireless transmission, a large amount of electromagnetic waves will be generated, which will affect the human body. Therefore, communication electronic products must pass the human body absorption rate (Specific absorption rate, SAR) test. Specifically, the practice in the prior art is to Each group of antennas is equipped with a group of induction devic

Abstract

The invention discloses a communication device which comprises a plurality of antennas, a sensing unit, a plurality of radio frequency circuits and a sensing module. The sensing unit is electrically connected to the grounding end through at least one grounding capacitor, and the sensing unit is also used for coupling and isolating each antenna; each radio frequency circuit in the plurality of radio frequency circuits is electrically connected to each corresponding antenna, and the plurality of radio frequency circuits are used for generating radio frequency signals; and the sensing module is electrically connected to the sensing unit through an inductor, and the sensing module is used for sensing the spacing distance between the sensing unit and an external object through the sensing unitand generating a distance signal according to the spacing distance.

Description

technical field [0001] The invention relates to a communication device, in particular to a communication device with multiple antennas in the same frequency band or different frequency bands. Background technique [0002] Generally speaking, in order to cope with various wireless transmission specifications and MIMO (Multiple Input and Multiple Output) technologies that will be developed at present and in the future, electronic products with communication functions usually install multiple sets of antennas in the same frequency band or different frequency bands to cover the same or different frequency bands. Different frequency bands, so as to meet the specifications of various communication protocols or the requirements of MIMO technology. However, when installing multiple sets of antennas in the same frequency band or different frequency bands in communication electronic products with limited space, isolation must be done so that the communication functions will not be aff...
