DIFF Subgroup
H01Q 11/12 Resonant antennas
Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Electrically-long antennas having dimensions more than twice the shortest operating wavelength and consisting of conductive active radiating elements > Resonant antennas
CPC:
Electrically-long antennas having dimensions more than twice the shortest operating wavelength and consisting of conductive active radiating elements (leaky waveguides antennas or slot antennas H01Q13/00) > Resonant antennas
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
