摘要： An electric power receiving and supplying circuit comprises: a microstrip patch antenna, having a feeding point, for receiving a microwave signal and supplying an electric power; a rectifier, for rectifying the electric power, having: a first diode having an anode, connected to the feeding point, and a cathode; a second diode having a cathode, connected to the cathode of the first diode through a junction point, and an anode; and a high-frequency grounding circuit for high-frequency-grounding the anode of the second diode, and a lowpass filter for low-pass filtering the rectified electric power to supply a dc supply power. The circuit mentioned above may further comprise: a third diode having an anode connected to the high frequency grounding circuit, and a cathode connected to the junction point, or may further comprise: a third diode having an anode connected to the high frequency grounding circuit, and a cathode connected to the anode of the second diode, or may further comprise: a third diode having a cathode connected to the feeding point and a anode connected to the high frequency grounding circuit and the anode of the second diode. The above-mentioned circuit may further comprise a matching circuit for matching the antenna and the rectifying circuit.

摘要： A first responder for transmitting an identification signal in response to a microwave interrogation signal comprises an electric power receiving circuit for receiving the interrogation signal to produce a dc power, having a microstrip line antenna having a trapezoid shape whose upside has a width from 1/2 to 1/4 of a wavelength, and a rectifying circuit. The rectifying circuit may be modified. A second responder comprises an electric power receiving circuit having a microstrip line antenna from the received microwave signal, a power supplying circuit for supplying a dc power in the vertical and horizontal positions of the responder against a polarizing plane of the microwave signal, an identification signal generation circuit for transmitting an identification signal through the antenna with given polarization plane by detecting the responder attitude. A third responder receives a microwave signal circularly polarized or polarized in vertical and horizontal directions and transmits the identification signal in either of vertical or horizontal directions according to the received microwave intensity in both directions.
