Electronic device for measuring biometric signal and method of operating the same

An electronic device comprising:

• a sensor module including at least one sensor;
• a communication circuit configured to be connectable to a plurality of antennas, and configured to support ultra-wide band (UWB) communication, wherein the plurality of antennas comprises at least two antennas that are disposed at different positions on and/or inside a housing of the electronic device;
• at least one processor, comprising processor circuitry, operatively coupled with the sensor module and the communication circuit;
• and
• memory storing instructions,
• wherein the instructions, when executed by the at least one processor individually and/or collectively, cause the electronic device to:
• identify a mounting state of the electronic device based on sensor data received from the sensor module;
• based at least in part on positions of the plurality of antennas that are disposed on and/or inside the housing of the electronic device, select at least one antenna combination including at least one transmission antenna and at least one reception antenna from among the plurality of antennas according to the mounting state;
• obtain a radar signal related to a measurement target from the communication circuit through the at least one antenna combination;
• obtain a biometric signal from the obtained radar signal;
• evaluate a signal quality of the biometric signal;
• and
• adjust control parameters for an antenna combination selected from among the at least one antenna combination according to the sensor data, the radar signal, and the signal quality of the biometric signal.
