H01Q 9/22

Rigid rod or equivalent tubular element or elements

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Electrically-short antennas having dimensions not more than twice the operating wavelength and consisting of conductive active radiating elements > Resonant antennas > with feed intermediate between the extremities of the antenna, e.g. centre-fed dipole > Two collinear substantially straight active elements; Substantially straight single active elements > Rigid rod or equivalent tubular element or elements

CPC:

Electrically-short antennas having dimensions not more than twice the operating wavelength and consisting of conductive active radiating elements > Resonant antennas > with feed intermediate between the extremities of the antenna, e.g. centre-fed dipole (H01Q9/44 takes precedence) > Two collinear substantially straight active elements; Substantially straight single active elements (H01Q9/28 takes precedence) > Rigid rod or equivalent tubular element or elements

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