H01Q 9/32

Vertical arrangement of element (H01Q9/40 takes precedence)

Introduced: September 1968

Title

Titles differ between systems:

IPC: Vertical arrangement of element

CPC: Vertical arrangement of element (H01Q9/40 takes precedence)

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 to end of elongated active element, e.g. unipole > Vertical arrangement of element

CPC:

Electrically-short antennas having dimensions not more than twice the operating wavelength and consisting of conductive active radiating elements > Resonant antennas > with feed to end of elongated active element, e.g. unipole (H01Q9/44 takes precedence) > Vertical arrangement of element (H01Q9/40 takes precedence)

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.
