DIFF Subgroup
H01P 1/17 for producing a continuously rotating polarisation, e.g. circular polarisation
Introduced: July 1974
Full Title
Full titles differ between systems:
IPC:
Auxiliary devices > for rotating the plane of polarisation > for producing a continuously rotating polarisation, e.g. circular polarisation
CPC:
Auxiliary devices (coupling devices of the waveguide type H01P5/00) > for rotating the plane of polarisation > for producing a continuously rotating polarisation, e.g. circular polarisation
Of 4 combined children, 0 exist in both systems.
4 codes are CPC-only extensions.
