Abstract

PURPOSE:To enable to adjust the reception state with remote operation, by making variable the directivity or direction performance of antenna in response to the reception signal through the provision of the receiver to the antenna unit. CONSTITUTION:The loop antenna A is divided into a plurality of conductors A1- A4, one end of the feeding lines PF1-PF4 is connected to a plurality of division points, the switch circuit is connected to another end of feeding line, the impedance element and feeding terminal are connected to the switch circuit, and the control circuit selecting and controlling a plurality of switch circuits is provided. Further, the pulse signal transmitted from the transmitter is received, this reception signal changes the state of the ring counter, FF and logic circuit, enabling to make variable the directivity or directive performance of antenna.
