Abstract:
A patch radiator antenna array comprising:a single continuous conductive ground plane element having a major surface;a first continuous dielectric planar member disposed over the major surface of the ground plane element and having embedded therein isolated electrically conductive regions;a plurality of feed patch radiator elements disposed on a face of the first dielectric member remote from the ground plane element, each feed patch radiator element defining a respective feed patch area and adapted to be coupled to at least one of an RF signal source and an RF receiver, with the isolated electrically conductive regions being disposed around a respective feed patch area so as to completely surround the feed patch area;a second continuous dielectric planar member disposed over the plurality of feed patch radiator elements;a plurality of coupled patch radiator elements disposed on the second dielectric member remote from the feed patch radiator elements, each coupled patch radiator element associated with a corresponding feed patch radiator element,wherein the first dielectric planar member has a first dielectric constant that is greater than a second dielectric constant of the second dielectric planar member.
