Abstract:
1. An antenna ( 100 - 3300 ), comprising: a dielectric layer defining a first side and a second side; one or more conductive ground plane elements disposed on the first side of the dielectric layer; a two-dimensional array of spaced-apart, radiating patches disposed on the second side of the dielectric layer; one or more microstrips disposed on the second side of the dielectric layer and connected directly to at least one corner of each of a plurality of immediately adjacent patches, such that each of the patches is directly coupled electrically to immediately adjacent patches in each of the two dimensions, wherein the one or more microstrips, the one or more ground plane elements, and the plurality of patches are at least configured to form at least one resonant cavity and wherein a standing wave is formed in the at least one resonant cavity whereby at least one node of the standing wave exists along at least a portion of the one or more microstrips and wherein the dielectric layer, the one or more ground plane elements, the plurality of patches and the one or more microstrips act collectively as a resonator.
