Abstract: An electronic device is provided. The electronic device includes a first conductive layer, a second conductive layer that is formed to be opposite to the first conductive layer. The second conductive layer includes conductors that are electrically separated, and one or more photo-conductive members connected between the conductors. The electronic device further includes an insulating layer that is interposed between the first conductive layer and the second conductive layer, one or more light sources positioned to face the one or more photo-conductive members, and a control circuit. The control circuit outputs a specified light through the light source such that an electric conductivity of the photo-conductive member increases in response to a light, from among the photo-conductive members and some conductors are electrically connected with the photo-conductive member, and a capacitance value between the first conductive layer and the second conductive layer is changed.

Abstract: A transmission of a sounding reference signal by an electronic device is provided. A method of an electronic device includes transmitting a signal via a first antenna subset including at least one of a plurality of antennas, measuring an emission environment of the plurality of antennas, using the signal, determining at least one antenna to be used for transmitting a sounding reference signal (SRS), based on the emission environment, and transmitting the SRS via the at least one determined antenna. The emission environment includes a strength of a reflected signal that corresponds to the signal and is reflected by the first antenna subset, or a strength of a reception signal that corresponds to the signal and is received by a second antenna subset including at least one remaining antenna.
