Mobile Telephone Device

摘要

A mobile telephone device capable of acquiring a high sensitivity over a wide band without being obstructed by the antenna when in use and while being held by the hand of a user. In this device, a variable tuning circuit ( 106 ) and a band switching circuit ( 107 ) are connected with a loop element ( 104 ) acting as a TV receiving on-board antenna. The variable tuning circuit ( 106 ) is controlled with a tuning voltage ( 110 ) generated in a TV receiving circuit ( 109 ). A channel control unit ( 111 ) sets the received channel of the TV receiving circuit ( 109 ) and controls the band switching circuit ( 107 ) with a band switching signal ( 112 ).
