Abstract
Various embodiments of the present invention relate to an electronic device and a method for controlling transmission power, the electronic device comprising: an amplification circuit; an antenna electrically connected to the amplification circuit; a variable element capable of adjusting the impedance between the amplification circuit and the antenna; and a control circuit, wherein the control circuit can be configured to: output a signal, having been amplified by a designated gain by means of the amplification circuit, to an external electronic device by using the antenna, in a state in which the variable element is adjusted to a first impedance; detect the approach of an external object during outputting of the signal; in response to the detection of the approach of the external object, check control information by which the first impedance of the variable element can be changed to a second impedance; and adjust the designated gain on the basis of at least the control information.
