An antenna, comprising: a plurality of electrically conducting plates; at least one of the plates perforated by an opening having a closed outline defining an aperture area; an electrically conducting member positioned between two of the plates, adjoining and centered upon the aperture area; the conducting member having a surface area less than the aperture area; at least one feed element spaced between the two plates and abuttingly coupled to the conducting member; a plug of a dielectric material completely filing the aperture; the plug having a perimeter everywhere contiguous to the closed outline; insulating means electrically separating the conducting member and the feed element from the conducting plates; and means for attenuating radiation from the feed element.
