ABSTRACT:
This is a radar transponder in which an amplifying means using a FET amplifier is inserted between a receiving antenna and a detecting means. Further, the radar transponder has a receiving on/off control circuit which stops the operation of the amplifying means in transmitting a response signal in order to enhance the receiving sensitivity thereof. Also, the radar transponder mounts the amplifying means, and the detecting means via a metal body having resilience on an antenna housing. Each circuit unit of the radar transponder and connection wirings between each circuit unit are formed by flexible printed circuit boards.
