Abstract: An electronic device is provided and includes a first housing forming a portion of an outside surface of the electronic device, a second housing coupled with the first housing and forming another portion of the outside surface of the electronic device, an antenna formed in at least a portion of the second housing, a connector including one or more connection pins for connection with an external device, at least a portion of an outside surface of the connector being formed of a conductive member, an adjusting circuit electrically connected with, at least, the portion of the outside surface of the connector formed of the conductive member, wherein an impedance of the adjusting circuit is variable. The electronic device may further include a processor configured to vary the impedance of the adjusting circuit based on a signal to be output through the antenna, and output the signal through the antenna, with the impedance of the adjusting circuit being varied.

Abstract: A method of utilizing a background image of a portable terminal, and a portable terminal for implementing the method, are provided. The method includes displaying the background image, determining whether an input event is detected in the displayed background image, identifying a coordinate of an area in which the input event is detected upon detection of the input event, determining whether there exists a function mapped to the identified coordinate, and performing the function if there exists the function mapped to the identified coordinate.
