Abstract: An electronic device includes at least one processor, at least one antenna, and a wireless communication circuit electrically connected to the at least one processor and the at least one antenna. The wireless communication circuit includes a switch including a first terminal electrically connected to a path corresponding to a first frequency band, a second terminal electrically connected to a path corresponding to a second frequency band, and a third terminal selectively connected to a corresponding terminal of the first terminal and the second terminal and a filter circuit electrically connected between the third terminal and the at least one antenna and having a designated resonant frequency band. The wireless communication circuit selectively transmits a signal in one corresponding frequency band between the first frequency band and the second frequency band based on a terminal which is connected to the third terminal.
