Abstract

PURPOSE:To make the distribution of the amplitude of an aperture face uniform, by providing a dielectric ring which is arranged symmetrically in respect to rotation for the antenna axis along the edge of a main reflective mirror. CONSTITUTION:An antenna is formed by an approximately round main reflective mirror 1, which is constituted symmetrically in respect to rotation for the antenna axis, and a feeding means 2 with a reflector 3 which is provided in the approximate center in front of the reflective mirror 1 and is symmetrical in respect to rotation for the antenna axis. In this case, a dielectric ring 5 which is arranged symmetrically in respect to rotation for the antenna axis is provided along the edge of the reflective mirror 1. As a result, electeromagnetic waves are concentrated to the edge of the antenna to make the distribution of the amplitude of the aperture face uniform.
