Patent ID: 11863240
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An electronic device comprising:
a first antenna and a second antenna;
a communication circuit comprising a transceiver configured to generate at least one signal, at least one amplifier configured to amplify the generated signal, at least one duplexer configured to distinguish the amplified signals according to communication bands thereof, and at least one coupler configured to radiate the distinguished signals through at least one of the first antenna or the second antenna; and
a processor electrically connected to the first antenna, the second antenna, and the communication circuit,
wherein the processor is configured to:
control the communication circuit to output a first signal through the first antenna and acquire a second signal obtained through reflection of the first signal from the first antenna and a third signal acquired through reception of the first signal, output through the first antenna, through the second antenna,
identify a reflection coefficient obtained through reflection of the first signal from the first antenna and a transfer coefficient obtained through transmission of the first signal to the second antenna, based at least partially on the second signal and the third signal, and
perform a predetermined function according to a value corresponding to a distance between the electronic device and an external object, based at least partially on the reflection coefficient and the transfer coefficient,

wherein the communication circuit further comprises a switch disposed between a first coupler receiving the reflected second signal and a second coupler receiving the third signal and configured to switch at least one of the received second signal or the third signal to be transmitted to the transceiver.
