MONOPOLE ANTENNA WITH CLOSED CORE FOR MOBILE USE Russian patent published in 2016 - IPC H01Q9/30 

FIELD: antennas.

SUBSTANCE: present invention relates to antenna engineering. Monopole antenna has a closed core, a ground plane, a current-conducting coil wound around the core and having at least two turns. Coil has two ends, herewith the first end is secured on the core or outside it, and the second end is fixed outside the core and forms the first contact output for supply of the antenna. Antenna supply port comprises the second contact output connecting the ground plane with the core. Core can be made in the form of a ring, a rectangle, a polyhedron or an oval. Herewith the antenna is arranged partially inside the ground plane, which is part of a printed circuit board and is mechanically fixed on the printed circuit board. Antenna core is made of ferrite or hexaferrite, or from a magnet-dielectric and has an adjustable gap. Load to the antenna is connected through a matching circuit in the form of a strip line.

EFFECT: technical result is minimization of dimensional characteristics.
