Document Type and Number:
WIPO Patent Application WO/2022/087927
Kind Code:
A1
Abstract:
Provided are an antenna tuning apparatus and method, which relate to the technical field of communications and are used for reducing storage overheads and tuning delay in an antenna tuning process. The apparatus comprises: an impedance tuning circuit coupled to an antenna for providing impedance matching, wherein the impedance tuning circuit has a reference state, the reference state is one preset state among a plurality of states of the impedance tuning circuit, and the reference state is used for the measurement of a state parameter of the antenna; and an interface circuit for receiving a first control signal, wherein the first control signal is used for enabling the impedance tuning circuit to be in the reference state.
