Abstract: Various embodiments relate to an electronic device for supporting a finger pinch interaction using a return loss of a radio frequency signal and an operating method thereof. The electronic device is configured to measure a return loss of an antenna while radiating a radio frequency signal through the antenna and to detect whether a thumb and a finger touch each other within a predetermined distance from the antenna based on the measured return loss. Accordingly, there can be provided an interaction for the touch between the thumb and the finger.
