MULTIRANGE ANTENNA OF CIRCULAR POLARISATION WITH METAMATERIAL Russian patent published in 2013 - IPC H01Q13/00 

FIELD: radio engineering, communication.

SUBSTANCE: antenna comprises split circular antenna elements made of segments of circular planar conducting paths, a gap between neighbouring segments in places of their coupling makes 0.1-0.5 mm, a planar antenna element, formed in the inner circular antenna element, power supply facilities, which include a directional coupler, two pins, four sections of strip lines, connected with the planar antenna element and each with segments of circular antenna elements, the planar antenna element is equipped with four slots arranged from the edge to the centre. Besides, four sections of strip lines are arranged near edges of four slots in a symmetrical manner, and antenna elements and sections of strip lines are arranged on a common dielectric substrate, and the antenna base is made on the outer lining of the directional coupler on the basis of joined strip lines.

EFFECT: achievement of higher compactness and manufacturability of making a multirange MPA, miniatuarisation of a multirange MPA.
