Abstract

A crossed-slot antenna in a first ground plane has a first feed, in stripline form including a second ground plane, which underlies a portion of one of the orthogonal slots for exciting a first polarization. A conductive lip of the other slot extends through the plane of the first feed, and opens through the second ground plane. A second feed includes conductors underlying the extended other slot. In a preferred embodiment, the feeds for the first and second slots are balanced. In a particularly advantageous embodiment, an array of such crossed slots is co-located with an array of enhanced-gain patch antennas.
