Patent ID: 7539527

Claim:
An apparatus for matching an antenna of a mobile communication terminal, the apparatus comprising: an antenna; a switch connected to the antenna and configured to receive a first or second control signal; a first matching unit connected between the switch and an RF signal generating unit of the mobile communication terminal for matching a first impedance between the antenna and the RF signal generating unit if the antenna is adjacent to a display unit of the mobile communication terminal; a second matching unit connected between the switch and the RF signal generating unit for matching a second impedance between the antenna and the RF signal generating unit if the antenna is apart from the display unit; a sensing unit comprising a magnet and a Hall effect switch, wherein the Hall effect switch is configured to generate a first match signal if the antenna is adjacent to the display unit and generate a second match signal if the antenna is apart from the display unit; and a controller configured to generate the first control signal for connecting the first matching unit to the antenna in response to the first match signal and generate the second control signal for connecting the second matching unit to the antenna in response to the second match signal.
