Antenna in common use for multi-frequency band

Abstract

Abstract PURPOSE:To synthesize a desired radiation beam by constituting one main reflection mirror through the addition of a mirror face consisting of a part of a paraboloid of revolution and having a different focus of another mirror face at the center or a circumferential part of the latter mirror face whose mirror face is corrected. CONSTITUTION:The main reflection mirror 1 is constituted by combining partial mirror faces 2, 3, 4 and 5 consisting each of a part of the paraboloid of revolution. The partial mirror faces 2, 3 and 4 have a point F as a focus and a resolution center axis of each paraboloid of revolution is arranged in a different direction. The partialmirror face 5 is arranged at the circumferential part of the partial mirror faces 2, 3 and 4, uses a point F5 as a focus and adopts an axis Z5 as its revolution center axis. Moreover, a primary radiator system 10 at a high frequency band is arranged at the point F and a primary radiator system 11 at a low frequency band is arranged at the point F5. Then the system is constituted that the primary radiator system 10 irradiates mainly the partial mirror faces 2, 3 and 4 and the primary radiator system 11 irradiates entirely the main reflection mirror face 1.
