Abstract

PURPOSE:To obtain a required cancellation ratio over a relatively wide range by arranging a subordinate antenna in the opening surface of a main antenna. CONSTITUTION:A parabolic antenna is regarded as main antenna 1, and a horn antenna provided in the opening surface of main antenna 1 as subordinate antenna 2. When the distance between the centers of main antenna 1 and subordinate antenna 2 is (d) and wavelength to be used is (lambda), diameters of main antenna 1 and subordinate antenna 2 should be 20lambda and 2lambda, and (d) should be small, e.g. about 5lambda. Thus, a required cancellation ratio can be obtained over a relatively wide range.
