Summary:PROBLEM TO BE SOLVED: To obtain a spherical mirror antenna capable of avoiding blocking caused by a primary radiator.SOLUTION: An auxiliary lens 3 is disposed in such a manner that an optical path length from the phase center of the primary radiator to the auxiliary reflector when the auxiliary lens 3 functions as an auxiliary reflector equals an optical path length from the phase center of the primary radiator 4 to the auxiliary lens 3, and a beam directed from the auxiliary reflector toward an aperture plane of the primary radiator when the auxiliary lens 3 functions as the auxiliary reflector intersects with a beam radiated after reflected by the auxiliary lens 3 and directed toward the aperture plane, with an equal inclination and in an identical position on the aperture plane. The primary radiator 4 is disposed on the opposite side of the auxiliary lens 3 to a subreflector 2.
