Document Type and Number:
WIPO Patent Application WO/2023/017991
Kind Code:
A1
Abstract:
According to various embodiments, an electronic device comprises: an antenna; an antenna tuner; a transceiver; a power amplifier which is electrically connected to the antenna tuner and performs power amplification in accordance with impedance matching; and at least one processor operatively connected to the transceiver, the antenna tuner, and the power amplifier. The at least one processor may be set to: confirm the antenna reflection coefficient by setting a reference tuner code for the antenna tuner connected to the antenna on a signal path of the transceiver; and calculate the tuner code of the antenna tuner by the set mode on the basis of whether there is a change in the confirmed antenna reflection coefficient and the operation of at least one element in the antenna tuner, and perform impedance matching of the antenna.
