BROADBAND HORN-MICROSTRIP ANTENNA Russian patent published in 2009 - IPC H01Q13/02 

FIELD: physics, communication.

SUBSTANCE: invention concerns to VHF antennas. The second shunt is in addition entered into the broadband horn-microstrip antenna containing a megaphone, the resonator and the shunt, the megaphone has the shape of the square direct cylinder, and the resonator plate is executed from well spending material in the form of the circle sector which symmetry axis is perpendicular to two opposite lateral walls of a megaphone and transits through their symmetry axes. The sector vertex is added by symmetrically acting strip device, the situation and which sizes are determined by value of the given strip of working frequencies. The vertex of sector of a circle of a plate of the resonator is joined to the central conductor of a feeding coaxial line a trusty electrical link, and the feeding coaxial line is brought to a resonator plate through a lateral wall perpendicularly to it, and the exterior conductor of a line is anchored on a lateral wall by a trusty electrical link. The first and the second shunts, made from well-conducting material, join corners of sector of the resonator plate circle to corresponding lateral walls of a megaphone and is provided trusty mechanical and an electrical link.

EFFECT: making of the broadband three-band send-receive antenna with the underload dimensions, providing effective reception and signalling with macro-and microcell structure.
