1. A microwave electric power receiver for generating a DC power from a received microwave comprising:

  • two microstrip resonators formed on an upper surface of a planar dielectric substrate which includes a ground plate disposed on a lower surface, said microstrip resonators each having a line length 1/2 of a wavelength of the microwave to be received are arranged perpendicular to each other in a cross shape, each of said two microstrip resonators is split at a longitudinally central portion thereof into two portions, two rectification diodes are interposed respectively between the notched end portions of the corresponding microstrip resonators to be matched therewith; and

    wherein a choke coil is interposed between a cathode of at least one of the diodes and a positive output terminal and another choke coil is interposed between an anode of at least one of the diodes and a negative output terminal, said choke coils being formed on the dielectric substrate.
