Antenna beam switching sensing system, method and mobile terminal

Abstract

The present invention provides an antenna beam switching sensing system, method and mobile terminal, wherein the antenna beam switching sensing system includes: a baseband chip for generating and sending baseband communication signals; a radio frequency module connected to the baseband chip for receiving baseband The baseband communication signal sent by the chip is sent out through the antenna array in the radio frequency module; and the attribute parameters of the echo signal of the antenna array are obtained; the baseband chip is also used for, according to the attribute parameters of the echo signal generated by the antenna array and a preset Set parameters to obtain the sensing result of whether the antenna array is blocked. The antenna beam switching sensing system provided by the present invention uses the antenna unit in the antenna array as a detection antenna to quickly sense the influence of the external environment on the antenna array, which can reduce the area required for the antenna module and the components required for circuit design , complexity and cost, while reducing power consumption and heat generation; and can ensure the wireless communication effect and improve the user's wireless communication experience.
