Patch radiator with cavity backed slot
First Claim
1. A patch radiator for an antenna element comprising:
- a support structure; and
a polygonal plating of conductive material, operatively contacting the support structure, the polygonal plating having a polygon perimeter length and an aperture located therein having an aperture perimeter;
wherein configurations of the polygonal plating and the aperture are selected such that(i) a ratio of the polygon perimeter length to the area of the polygon is maximized; and
(ii) a ratio of the aperture perimeter to the aperture area is minimized.

Abstract
A patch radiator for use in beamformed or steerable antenna systems which maximizes upper frequency limit and simultaneously minimizes the lower frequency limit, by providing an annular patch configuration in which a central region of the patch element is devoid of material, whereby this central region is of a different shape from the shape of the exterior perimeter of the patch element. One possible configuration of such a patch radiator comprises a square exterior shape, enclosing a central circular region of removed material. In this manner, the upper frequency limit threshold tends to rise as the interior annular perimeter is reduced. Preferably, the exterior and interior perimeters have no interior angles of more than 180°.
