ABSTRACT:
A cellular telephone set is capable of receiving a plurality of broadcast waves while efficiently covering wide bands such as FM and TV broadcasts and reducing mutual effects on radio circuits if the cellular telephone set has the additional function of receiving FM and TV broadcasts and the antenna of the cellular telephone set is used to share receipt of FM and TV broadcasts. The cellular telephone set has an antenna, a radio unit selector switch branching a line connected to the antenna into two lines that are connected respectively to a switch and a cellular telephone set radio unit, and a plurality of impedance adjusting circuits connected parallel to the switch and associated with the broadcast waves, respectively. The switch selects one of the impedance adjusting circuits which is associated with the broadcast wave that is being currently received.
