Abstract:
Disclosed is an electronic device including an antenna including a radiating portion and a feeding portion connected to the radiating portion; a tunable element electrically connected to the radiating portion and configured to influence an electrical length of the radiating portion with respect to a specified frequency; an amplifier electrically connected to the feeding portion and configured to amplify a signal to be transmitted to an external electronic device through the radiating portion; and a control circuit electrically connected with the antenna, the tunable element, and the amplifier. The control circuit is configured to determine strength of a signal reflected from the radiating portion while the signal is transmitted to the external electronic device through the radiating portion; and adjust a value of the tunable element to reduce the strength of the reflected signal.
