PROBLEM TO BE SOLVED: To enlarge a specific band width, while shortening a slot width, even when separating a feed layer and a radiative element, and to improve return loss and an intercoupling amount, even when constituted in a polarized wave common usage. SOLUTION: A feed line 12 is formed on one surface of a dielectric substrate 11, and a grounding layer 13 is formed on the other surface of the dielectric substrate 11; a slot 14 in a butterfly shape is formed on the grounding layer 13 so as to be orthogonal to the feed line 12, and flat metal layers (patches) 16 and 18 are successively laminated via the dielectric substrates 15 and 17 on the grounding layer 13.
