Abstract

An antenna element includes a ground plane, a first conductive disk lying parallel with the ground plane and spaced therefrom, and a second conductive disk, larger than the first disk, more remote from the ground plane than the first disk. A electrical and thermal conducing element may make electrical and thermal contact with the ground plane and the first and second disks. A radome extends over the element and in thermal communication with the thermal element. A conductive or high-dielectric-constant planar wing is supported by the ground plane outside of the projection of the disks, with a central axis of the element lying in the plane of the wing. If two wings are present, one may be electrically conductive or dielectric and the other conductive or dielectric. The wings, when the element is arrayed, lie part-way between the centers of adjacent array elements.
