DIFF Subgroup
H01Q 11/06 Rhombic antennas; V-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 > Non-resonant antennas, e.g. travelling-wave antenna > Rhombic antennas; V-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) > Non-resonant antennas, e.g. travelling-wave antenna (Yagi antennas H01Q19/30) > Rhombic antennas; V-antennas
No child classifications to compare. This is a leaf node in both IPC and CPC.
