in which the selected sections are parallelly spaced

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 > with parts bent, folded, shaped or screened or with phasing impedances, to obtain desired phase relation of radiation from selected sections of the antenna or to obtain desired polarisation effects > in which the selected sections are parallelly spaced

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 > with parts bent, folded, shaped or screened or with phasing impedances, to obtain desired phase relation of radiation from selected sections of the antenna or to obtain desired polarisation effect (H01Q11/20 takes precedence) > in which the selected sections are parallelly spaced

No child classifications to compare. This is a leaf node in both IPC and CPC.
