H01Q19/136 - CPC Classification

Classification description:

Combinations of primary active antenna elements and units with secondary devices, e.g. with quasi-optical devices, for giving the antenna a desired directional characteristic using reflecting surfaces wherein the surfaces are concave the primary radiating source being a single radiating element, e.g. a dipole, a slot, a waveguide termination; Rear-feeds; Splash plate feeds cross-polarised
