1. A method for providing communication in an electronic device, the method comprising:

  • detecting at least one of contact or proximity with an object;

    determining whether an impedance of an antenna of the electronic device changes based on the detecting of the object;

    when the impedance changes and there is no data to transmit, transmitting at least one signal through the antenna for determining a control value for controlling a resonant frequency of a transceiver of the electronic device;

    measuring a reflected signal that is reflected through the antenna based on the transmitted at least one signal for determining the control value;

    determining the control value for controlling the resonant frequency of the transceiver based on the reflected signal; and

    controlling an impedance of an antenna of the electronic device based on the control value.
