Abstract

PURPOSE:To minimize the generation of multipath noise, by taking the received electromagnetic waves of an antenna connected to a receiver as the reference and switching the receiver to an antenna over the reference through the sequential comparison with the received electromagnetic waves of other antennas. CONSTITUTION:When an antenna switching circuit 7 connects an FM radio receiver 9 to a received antenna A1, a switching scanning circuit 8 switches antennas A2-A4 to a subreceiver 12 sequentially every given period with the scanning signal ep from a switching control circuit 15, the received input of the antennas A2-A4 is detected at a reception state detecting circuit 13, and a detection signal eo is given to a comparator 14. To the comparator 14, a reception state detecting signal er of the antenna A1 from a reception state detecting circuit 11 is inputted and it is compared with the signal eo. When any of the reception state detecting signal eo of the antennas A2-A4 is over the signal er, the H level signal is fed to a switching control circuit 15 at the circuit 14, and the circuit 15 feeds a switching control signal ee to the circuit 7, where the receiver 9 is switched to an antenna over the reception state of the antenna A1.
