GUIDE ANTENNA WITH LARGE BEAM WIDTH Russian patent published in 1996 - IPC

FIELD: antenna equipment. SUBSTANCE: antenna uses a circular guide with H-wave 11 and a metal pipe coaxially positioned around it, making up a coaxial resonator, with an annular slot cut in its end face wall, excited by a T-wave. The planes of opening of the annular slot and circular guide coincide. Electrical coupling of the coaxial resonator with the circular guide is accomplished by means of two coupling loops, located inside the coaxial resonator and secured by a dielectric positioned in the circular guide. EFFECT: improved design. 3 dwg
