Abstract

The invention provides a multiplexing antenna and an antenna multiplexing method. The multiplexing antenna comprises an antenna unit and a signal separation circuit. The antenna unit is connected with a signal input end of the signal separation circuit and is used for receiving a superposed signal and transmitting the received superposed signal to the signal separation circuit through the signal input end. The signal separation circuit is used for separating the superposed signal into an antenna signal and a capacitance sensor signal. The method comprises the steps of receiving the superposed signal of the antenna signal and the capacitance sensor signal; and extracting the antenna signal and the capacitance sensor signal from the superposed signal according to working frequencies of the antenna unit and a capacitance sensor in the multiplexing antenna. According to the multiplexing antenna in the embodiment of the invention, functions of the antenna unit and the capacitance sensor can be realized at the same time and the antenna unit and the capacitance sensor are multiplexed, so the occupied space is small and the cost is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a multiplexing antenna and an antenna multiplexing method. Background technique [0002] Common application scenarios of capacitive sensors in mobile terminals include: 1) Detect the distance of the human body through the capacitive sensor, and when the human body approaches the mobile terminal, reduce the transmission power of the antenna to reduce the impact on the human body; to match the switching between left and right hand modes on the interface of the mobile terminal. [0003] In the prior art, the capacitive sensor and the antenna are generally independent and separate modules or modules assembled together. The two units are installed inside the mobile terminal, occupying a lot of space, high cost, and the distance between the two units is very close. Capacitive sensors can significantly affect the performance of the antenna. Contents of the invention ...
