Patent ID: 6839028

Claim:
A microstrip antenna, comprising: a ground plane; a dielectric layer having a first surface overlying said ground plane, and a second surface opposing said first surface; a substantially planar and electrically conductive layer overlying said second surface, said electrically conductive layer including a plurality of substantially co-planar patches of differing widths, each of said plurality of patches being connected via one or more junctions to at least another of said plurality patches; a first patch among said plurality of patches is disposed between opposing edges of a second patch and a third patch of said plurality of patches, wherein said first patch has a narrower width compared to widths of said second and third patches so that respective junctions formed between the first and second patch, and the first and third patch define discontinuities in width therebetween; a feed disposed in the first patch and configured to connect to a coaxial cable; and wherein said respective junctions formed between the first and second patch, and the first and the third patch are symmetrically disposed about the first patch.
