Abstract

PURPOSE:To reduce the cross coupling by making equal the secondary emittion performance, by fitting the metal piece of band or line shape. toward the direction tying the horn antenna center axis of a plurality surrounding the reflection mirror symmetry in rotation or toward orthogonal direction to this. CONSTITUTION:The antenna of Gregorian form is constituted by the primary radiator 1 having four horn antennas A to D, major reflection mirror 2m and sub- reflection mirror 3. With this constitution, on the opening of the antennas A to D detecting the tracking signal toward horizontal and vertical direction, the metal piece 5 consisting of the metal or line is provided while taking parallel with the direction r tying the center axis of antenna and the center of the antennas A to D. Or, in some cases, it can be toward the direction c other than the direction r. Thus, the secondary radiation performance of the polarized waves in parallel with the direction tying the center of the antennas or orthogonal to it can be made equal and the cross coupling can be reduced.
