DIFF Subgroup
H01Q 9/42

with folded element, the folded parts being spaced apart a small fraction of the operating wavelength

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 to end of elongated active element, e.g. unipole > with folded element, the folded parts being spaced apart a small fraction of the operating wavelength

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) > with folded element, the folded parts being spaced apart a small fraction of the operating wavelength

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

IPC defines codes here since 1980.
