ELECTRONIC DEVICE AND METHOD FOR DETECTING OBJECT

WIPO Patent Application WO/2024/010239

A1

According to embodiments, an electronic device may comprise: a processor; a radio frequency (RF) transceiver; a power amplifier (PA); a dual bidirectional coupler; and an antenna connected to the dual bidirectional coupler. The processor may be configured to transmit a first signal in a first frequency band as first transmission power through the PA, the dual bidirectional coupler, and the antenna, by controlling the RF transceiver. The processor may be configured to transmit a second signal in a second frequency band lower than the first frequency band through the dual bidirectional coupler and the antenna, while the first signal is transmitted, by controlling the RF transceiver. The processor may be configured to identify a forward coupling signal of the second signal and a reverse coupling signal of the second signal from among signals obtained from the dual bidirectional coupler, by controlling the RF transceiver.
