Abstract

The invention provides an antenna circuit comprising a first antenna transmit-receive path and at least one second antenna transmit-receive path, a first signal gain path is arranged between the firstantenna transmit-receive path and the at least one second antenna transmit-receive path, and the signal input end of the first signal gain path is electrically connected with the second antenna transmit-receive path. The signal output end of the first signal gain path is electrically connected with the first antenna transmit-receive path, and the first signal gain path is used for collecting signals on the second antenna transmit-receive path and filtering the signals to provide the signals for the first antenna transmit-receive path, so that when the first antenna transmit-receive path works, the antenna with at least two frequency bands can be used for receiving signals, thereby improving the utilization rate of the antenna when the antenna circuit works.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an antenna circuit and a mobile terminal. Background technique [0002] With the development of technology, the communication system has been continuously upgraded. Now most mobile phones support 5G, and the number of antennas has also increased sharply. The original 2-3 antennas have become 9-10 antennas, or even 20 antennas. There are many antennas on the 5G project, and many of them have similar functions and working frequency bands. For example, the working frequencies of antennas supporting intermediate frequency and high frequency are relatively close; for example, due to issues such as platform and device selection, there will be multiple working frequencies close to antenna. [0003] However, in the prior art, in a non-carrier aggregation working scenario, when a single frequency band is working, only the antenna related to this frequency band is working, and other...
