LOW PROFILE PHASED SATELLITE ANTENNA Russian patent published in 2023 - IPC H01Q21/00 

FIELD: radio engineering.

SUBSTANCE: invention is used for receiving and transmitting a signal of satellite frequencies on fixed and moving objects. A receiving/transmitting phased satellite antenna of circular polarization is proposed, comprising n passive microstrip structures, consisting of dielectric plates, on the surface of which metal passive elements are located, and the plates are fastened together, and the passive elements, starting from the first plate from the bottom, are shifted in one direction, a metal grounding plate, on the upper surface of which a dielectric with active microstrip elements is fixed, which forms an active ordered structure, and feeding probes are brought to the lower surface, which have an electrical connection with the active elements, the signals from the probes enter the first multichannel group waveguide with perturbation elements, at the same time, each waveguide channel in the lower part has one via for the signal output, characterized in that it comprises the second and third multichannel group waveguides, a device for adjusting the physical length of the delay lines and group adders of signals of left and right polarization.

EFFECT: reduced dimensions of the satellite dish.
