Abstract
Receiver configuration for microwave signals with a receiver antenna, a rectifier circuit and a detector circuit, wherein only one single antenna is provided to receive a vertically polarized energy signal and a horizontally polarized data signal. It has separate detector circuits available for the energy signal and the data signal. The detector circuit for the energy signal consists of a voltage doubling circuit to generate an operating voltage and the detector circuit for the data signal consists of a diode with a shunt resistor to generate a modulated DC voltage.
