ABSTRACT:
A segmented patch antenna has a dielectric material substrate, a plurality of primary electrically conductive segments consecutively disposed on the dielectric material substrate and spaced apart so that a portion of the substrate is exposed between any pair of adjacent primary segments, and a layer of dielectric material disposed over the primary segments. Secondary electrically conductive segments are disposed over the layer of dielectric material wherein each secondary segment corresponds to a pair of adjacent primary segments. Each secondary segment overlaps a portion of each primary segment of the corresponding pair of adjacent primary segments to which that secondary segments corresponds. The overlap of each secondary segment with a portion of each primary segment in a pair of adjacent primary segments produces a plurality of capacitive gaps that capacitively couple the primary and secondary segments together to define a single antenna.
