Abstract: Disclosed is an antenna module which includes a printed circuit board, a first antenna group including first and second sensing antennas disposed on a first surface of the printed circuit board and transmitting and receiving a first signal, a second antenna including antenna elements disposed on the first surface between the first and second sensing antennas, and a processor coupled to the printed circuit board, the first antenna group, and the second antenna group. The processor obtains information about a distance between an external object and the antenna module, based on the first signal transmitted and received through the first antenna group and transmits a second signal through the second antenna group with a first transmit power less than or equal to a first maximum power set to correspond to the first distance when the external object is within a first distance from the antenna module.
