Radar transponder
First Claim
1. A radar transponder having a receiving unit which is responsive to electric waves emitted from a radar and a transmitting unit which transmits a signal in response to the reception of said electric waves by said receiving unit, comprising:
- a power source circuit, a signal control circuit, a video amplifying circuit and a lamp LED display circuit, all formed on a respective deformable flexible wrap-around printed wiring board,wherein wiring connections between said power source, said signal control circuit and said video amplifying circuit, and said lamp LED display circuit are formed on at least one other deformable flexible wrap-around printed wiring board, andadditionally including a support member having a pair of opposing support surfaces, and wherein said power source circuit and said signal control circuit are formed on first and second deformable flexible wrap-around printed wiring boards respectively located on said pair of opposing support surfaces and wherein said video amplifying circuit and said lamp LED display circuit are formed on third and fourth deformable flexible wrap-around printed wiring boards respectively located on said pair of opposing support surfaces a predetermined distance away from said first and second deformable flexible wrap-around printed wiring board.

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.
