H01Q 11/04

with parts bent, folded, shaped, screened or electrically loaded to obtain desired phase relation of radiation from selected sections of the antenna (H01Q11/06 – H01Q11/10 take precedence)

Introduced: September 1968

Title

Titles differ between systems:

IPC: with parts bent, folded, shaped, screened or electrically loaded to obtain desired phase relation of radiation from selected sections of the antenna

CPC: with parts bent, folded, shaped, screened or electrically loaded to obtain desired phase relation of radiation from selected sections of the antenna (H01Q11/06 H01Q11/10 take precedence)

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 > Non-resonant antennas, e.g. travelling-wave antenna > with parts bent, folded, shaped, screened or electrically loaded to obtain desired phase relation of radiation from selected sections of the antenna

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) > Non-resonant antennas, e.g. travelling-wave antenna (Yagi antennas H01Q19/30) > with parts bent, folded, shaped, screened or electrically loaded to obtain desired phase relation of radiation from selected sections of the antenna (H01Q11/06 – H01Q11/10 take precedence)
