Method of outputting a signal using an antenna disposed adjacent to a conductive member of a connector and an electronic device using the same

An electronic device, comprising:

• an antenna connected with a feeding circuit for wireless communication;
• a communication circuit connected with the antenna and configured to output signals of a first frequency band and a second frequency band through the antenna;
• a conductive member disposed adjacent the antenna;
• a universal serial bus (USB) connector including one or more connection pins for connection with an external device received in the conductive member;
• a first filter circuit connected with the conductive member and capable of passing the signals of the first frequency band and the second frequency band;
• a first matching circuit corresponding to the first frequency band and connected directly to at least one ground;
• a second matching circuit corresponding to the second frequency band and connected directly to the at least one ground;
• a switching circuit configured to connect the conductive member, via the first filter circuit with at least one of the first matching circuit or the second matching circuit;
• and
• a processor configured to:
• control the switching circuit to connect the conductive member, via the first filter circuit, with at least one of the first matching circuit or the second matching circuit based on a signal to be output through the antenna, and
• output the signal through the antenna, with the conductive member being connected with the at least one of the first matching circuit or the second matching circuit.

An electronic device, comprising:

• 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 and connected with a feeding circuit for wireless communication;
• a universal serial bus (USB) connector including one or more connection pins for connection with an external device, at least a portion of an outside surface of the USB connector being formed of a conductive member;
• an adjusting circuit electrically connected to a portion of an outside surface of the USB connector formed of a conductive member via a first capacitor and connected directly to at least one ground of the electronic device;
• and
• a processor configured to:
• based on detecting a connection with the external device through the USB connector, control an 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 controlled.
