Abstract
A flat planar antenna formed from a flat this substrate coated on one surface with a electrically conductive material except for a first uncoated funnel shaped cavity with a large mouth beginning along one outer surface of the substrate and diminishing in cross-section toward the center of the substrate with a diminishing width down to an extended neck portion which extends to an outer substrate surface normal or parallel to the substrate surface adjacent to the mouth. A smaller tuning cavity may be positioned over the neck portion adjacent to the edge of the substrate. The antenna may have feed lines plated on the opposite surface from the funnel shaped cavity, hard wired through the substrate to the opposite side thereof or formed by micro stripline techniques. A second embodiment employs unplated side cavities between the funnel unplated area and the edges of the substrate normal to the funnel mouth.
