MULTI-RESONANT UNIDIRECTIONAL DIPOLE ANTENNA Russian patent published in 2014 - IPC H01Q11/10 

FIELD: radio engineering, communication.

SUBSTANCE: in the method a V-shaped multi-resonant unidirectional dipole antenna has a pair of hollow cones whose vertices face each other and a feed line; the cones are formed by 2N metal strips, which are dipole arms and are arranged in pairs opposite each other on the lateral surfaces of the cones; a metal reflector; the inner volume of said cones is divided by circular plates parallel to the base of the cone into a row of cavities filled with a dielectric with a given relative permittivity and which form a series chain of semiconductor hollow resonators whose resonance frequencies form a log-periodic sequence or a sequence which is close to log-periodic.

EFFECT: low standing-wave factor of the antenna at the input, low level of backscattered radiation and achieving a constant beam shape in a wide frequency range and providing a constant phase centre of the antenna system.
