A reception control system for automobiles according to the present invention includes tuners for a plurality of receivers for receiving various types of waves including at least an AM/FM broadcast wave, a TV broadcast wave and a GPS wave. The tuners are separated from receiver bodies and integrally incorporated into an antenna section (a plurality of antenna elements&plus;an AM/FM reception circuit&plus;a TV reception circuit) including at least a plurality of antenna elements. The tuners are supplied with a digital control signal through a LAN provided in an automobile thereby to control reception of waves.

Reception control system for automobile

The beam steering antenna unit of the present invention is constituted to determine the antenna directivity in the direction of the broadcast tower from which the electric wave currently being received is sent, by carrying out the selective combination of plural antenna elements, and controlling the phase relations between the RF signals of each band received with the above antenna elements based on the objective broadcast station data obtainable from the tuner, broadcast tower position data obtainable from the broadcast tower data base, and the present position information obtainable from the GPS receiver in receiving the FM/AM band, TV band, etc.
