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 > having two or more spaced reflecting surfaces > comprising one main concave reflecting surface associated with an auxiliary reflecting surface

CPC:

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 > having two or more spaced reflecting surfaces (H01Q19/20 takes precedence) > comprising one main concave reflecting surface associated with an auxiliary reflecting surface

CPC subdivides this area 4x more granularly than IPC with 3 additional codes.

3 codes are CPC-only extensions.

IPC defines codes here since 1980.
