  • Remote identification device
    Patent number: 5563589
    Abstract: In a remote identification device, an interrogator sends a microwave signal to a responder, the interrogation wave signal being modulated. At each period of the modulation signal of the interrogation wave signal, the responder accumulates the energy conveyed by this signal, the energy received being converted into supply voltage to be used to encode and transmit a response microwave signal to the interrogator. This may be used for the identification of objects by a radar signal.
