アンテナ装置。In a Cassegrain or parabolic antenna device equipped with a support column having an elliptical cross section that supports a sub-reflector or a primary radiator in front of a main reflector and blocks the passage of radio waves, the length of the ellipse of the support column is A radio wave absorber attached to the outer periphery of the tip facing the main reflecting mirror, and a radio wave absorber attached to the outer periphery of the tip of the elliptical minor axis of the support column extending in the direction of the main reflecting mirror parallel to the direction of radio wave propagation, the tip being longer than the wavelength. What is claimed is: 1. An antenna device characterized by comprising two flat scattering plates observing an irregular shape consisting of sides.
