INTEGRATED ANTENNA DEVICE Russian patent published in 2014 - IPC H01Q7/04 H01Q11/08 

FIELD: radio engineering, communication.

SUBSTANCE: integrated antenna device consists of a double-turn or multiple-turn helical cone-shaped radiator with apex angle of the cone α and a reflector-shield with diameter B, the device including another one or more cone-shaped radiators with apex angle β<α, for which the diameter of the upper base of the lower radiator is equal to the diameter of the lower base of the upper radiator and is superimposed with it, and a reradiator in form of a metal ring with diameter A<B and lying at a distance h=λ/4 parallel to the reflector-shield on the side of the cone-shaped radiators without galvanic coupling with the main reflector-shield, where λ is the wavelength of the operating range.

EFFECT: wider operating frequency band.
