Title

Titles differ between systems:

IPC: by electrical means

CPC: by electrical means (active lenses or reflecting arrays H01Q3/46)

Full Title

Full titles differ between systems:

IPC:

Arrangements for changing or varying the orientation or the shape of the directional pattern of the waves radiated from an antenna or antenna system > varying the relative phase or relative amplitude of energisation between two or more active radiating elements; varying the distribution of energy across a radiating aperture > varying the phase > by electrical means

CPC:

Arrangements for changing or varying the orientation or the shape of the directional pattern of the waves radiated from an antenna or antenna system > varying the relative phase or relative amplitude of energisation between two or more active radiating elements; varying the distribution of energy across a radiating aperture ( H01Q3/22, H01Q3/24 take precedence) > varying the phase > by electrical means (active lenses or reflecting arrays H01Q3/46)

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 1980.
