H01Q9/24 - CPC Classification

Classification description:

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 Shunt feed arrangements to single active elements, e.g. for delta matching
