H01Q 9/26 with folded element or elements, the folded parts being spaced apart a small fraction of operating wavelength (resonant loop antennas H01Q7/00)
Introduced: September 1968
Title
Titles differ between systems:
IPC: with folded element or elements, the folded parts being spaced apart a small fraction of operating wavelength
CPC: with folded element or elements, the folded parts being spaced apart a small fraction of operating wavelength (resonant loop antennas H01Q7/00)
Full Title
Full titles differ between systems:
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 > with folded element or elements, the folded parts being spaced apart a small fraction of operating wavelength
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) > with folded element or elements, the folded parts being spaced apart a small fraction of operating wavelength (resonant loop antennas H01Q7/00)
Of 2 combined children, 1 exist in both systems.
1 codes are CPC-only extensions.
IPC defines codes here since 1980.
