WIDEBAND CIRCULAR ANTENNA ARRAY Russian patent published in 2010 - IPC H01Q21/00 

FIELD: radio engineering.

SUBSTANCE: wideband circular antenna array contains at least one flat dielectric base with metallised layers in which there is excitation system and radiating aperture connected to it. Radiating aperture is made of n dipole radiators (curved dipoles (elements)), where n≥2, forming closed curve of the second order, the current-carrying 1 and screen 3 semi-dipoles are located in parallel planes located from each other at distance d determined with electrical parameters of antenna array, and can be partially or fully overlapped; at that, metallised layers of wideband circular antenna array are made on the outside and envelop dielectric base with excitation system. If the number of antenna arrays is more than one, they form volumetric system of interconnected antenna arrays.

EFFECT: development of wideband omnidirectional antenna array with high transmitted power and horizontal polarisation, wideband antenna array with high transmitted power and with vertical polarisation and wideband omnidirectional antenna system with vertical and horizontal polarisation and high transmitted power.
