Abstract: An antenna switching method of an electronic device is provided. The antenna switching method includes measuring a transmit power variation of a first antenna, monitoring characteristics of received signals of both the first antenna and a second antenna, determining a comparison result by comparing the characteristics of the received signals of both the first antenna and the second antenna when the transmit power variation is greater than or equal to a threshold value, and switching a transmitting antenna based on at least the comparison result.
