Title

Titles differ between systems:

IPC: the primary radiating source being a single radiating element, e.g. a dipole, a slot, a waveguide termination

CPC: the primary radiating source being a single radiating element, e.g. a dipole, a slot, a waveguide termination (H01Q19/15 takes precedence)

Full Title

Full titles differ between systems:

IPC:

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

CPC:
