MOBILE COMMUNICATION TERMINAL FOR HAVING ANTENNA CAPABILITY ACCORDING TO ACTION CHANNEL

摘要

A mobile terminal for securing antenna performance according to a radio signal operation channel is provided to obtain desired antenna performance by overcoming a bandwidth problem of an antenna with an insufficient antenna space in a mobile terminal. A wireless communication unit(24) transmits/receives a radio signal to/from a base station through an antenna(ANT). First and second antenna matching circuit units(27,28) correct an impedance difference between the wireless communication unit and the antenna(ANT). A switching unit(26) selectively connects one of connection terminals connected with the first and second antenna matching circuit units(27,28) to the wireless communication unit according to a switching control signal inputted to a select terminal. An operation channel processing unit(211) detects an operation channel of the radio signal inputted through the wireless communication unit and establishes an operation channel of the radio signal transmitted through the wireless communication unit. A switching controller(212) outputs the switching control signal by the operation channel of the radio signal to the switching unit.
