Abstract

The present application provides a terminal device and a communication method, which can improve the antenna mutual interference phenomenon in the terminal device. The terminal equipment includes: a first antenna and a second antenna; a first signal link and a matching link, and the matching link includes a matching network; a switch switching unit; the switch switching unit is used to switch the first antenna from the first The signal link is switched to the matching link, and the second antenna is switched to the first signal link at or after the first moment; wherein, the matching network is configured such that the difference between the first impedance and the second impedance is less than The preset threshold value, the first impedance is the impedance between the first output terminal of the switching unit and the ground when the first antenna is switched to the matching link, and the second impedance is the impedance when the first antenna is switched to the first signal In the case of a link, switch the impedance between the first output terminal of the switching unit and the ground.

Description

technical field [0001] The present application relates to the communication field, in particular to a communication method and a terminal device. Background technique [0002] Multiple antennas are usually configured in a terminal device, and completely independent work cannot be achieved due to the mutual influence of the electromagnetic fields between the antennas. For example, the change of the electromagnetic field of antenna A will affect the distribution of the electromagnetic field of antenna B, thus causing the amplitude and / or phase of the signal received and / or transmitted by antenna B to change, thereby causing fluctuation and decline of data throughput. [0003] In some scenarios, the antenna will switch between different signal links, and the switching will cause the impedance of the antenna to change, thereby affecting the field distribution of the antenna. Due to the influence of the same-frequency mutual interference between antennas, the impedance change of...
