Electronic device and method for performing wireless communication with external electronic device

An electronic device including: a battery; a signal converting circuit connected to the battery including first, second, third, and fourth switches of a bridge structure; a processor connected to the signal converting circuit; and an antenna connected to the signal converting circuit. The signal converting circuit is configured to: receive from the processor an input which selects a first communication scheme based on the received input while converting and providing to the antenna a direct current signal output from the battery to an alternate current signal; control the first and fourth switches to alternate in a high state and a low state; control the second and third switches in a different state which is different from the state of the first and fourth switches; and control two of the first, second, third, and fourth switches in the high state to alternate in an on state and an off state.
