<p>PURPOSE:To simplify the titled responder and to reduce it cost by providing an antenna on a resonance circuit by a coil and a capacitor consisting of a superconductive material. CONSTITUTION:An antenna 51 is provided on a resonance circuit by a coil 52 and a capacitor 53 consisting of the superconductive material. In this state, when a radio wave of a resonance frequency is received from the antenna 51, energy of its radio wave is stored in the resonance circuit. In this case, when the radio wave comes not to be received, the stored energy is emitted from the antenna 51, and an electric oscillation is attenuated. In such a way, by applying the resonance frequency, a location of a radio wave responder can be confirmed. Also, the enclosure 54 of the radio wave responder is formed in a shape of a thin plate, therefore, it becomes convenient to stick it to an object to be confirmed, or to be crimped. In such a way, the titled responder can be simplified, and also, its cost can be reduced.</p> |
