Abstract

PURPOSE:To make it possible to remove cross polarization in an arbitrary beam direction, by constituting an antenna device with two subreflection mirrors and the main reflection mirror and by not making the beam direction between two subreflection mirrors parallel with the beam direction of the main reflection mirror. CONSTITUTION:Radio waves radiated from conical horn 1 are reflected by subreflection mirrors 3 and 4 and are further reflected by main reflection mirror 2 and become the beam in a desired direction and are radiated. At this time, when NW is defined as the reference direction and the angle made by F0M and the reference direction, the angle made by M1M2 and the reference direction, angle made by M2M and the reference direction, and the distance from M1 to F1 are denoted as theta0, alpha, beta and l respectively, P1 = - sign (l) and P2 = signalpha (Xtheta-l/L0) are satisfied in respect to parameter P indicating the form of reflection mirrors (however, P1 and P2 indicate subreflection mirrors 3 and 4 respectively, and L0 is the distance from F0 to M0).
