PROBLEM TO BE SOLVED: To obtain a corner reflector antenna which can easily increase the antenna gain without extending the physical aperture area and can give a sharp main beam. SOLUTION: This corner reflector antenna comprises a corner reflector 3, which is constituted by arranging two conductor plates 1 and 2 of the same shape so as to form a prescribed opening angle, and an excitation element which is arranged in parallel with the junction side of conductor plates 1 and 2 or the junction side of extended faces of two conductor plates 1 and 2 and on a plane equally dividing the opening angle. In this case, one or plural passive elements are arranged in positions on the outside of the excitation element on the plane, where the excitation element is arranged, at prescribed intervals.
