Electronic device and method for controlling antenna

Abstract

An electronic device may include: a communication circuit configured to transmit and receive a signal using at least one frequency, at least one antenna circuit comprising antennas and matching circuits, a memory configured to store instructions, and at least one processor, comprising processing circuitry, wherein at least one processor, individually and/or collectively, is configured to execute the instructions and to cause the electronic device to: identify a network frequency used by the electronic device, identify radio access technology (RAT) used by the electronic device, select control signals corresponding to passive gain information higher than or equal to a specified gain among a plurality of pieces of passive gain information corresponding to a plurality of control signals, based on the identified frequency and the identified RAT, sort and manage the selected control signals, measure each of an in-phase component (I) and a quadrature component (Q) by applying the selected control signals, and select a control signal corresponding to an IQ measurement value close to a reference value, based on the in-phase and quadrature components (IQ) measured through the application of the control signals.
