Abstract:
A flat panel antenna comprising:a flat dielectric substrate having a first surface, a second surface that is generally parallel to said first surface, a first edge, and a second edge that is located generally opposite said first edge;a triangular-shaped metal radiating element on said first surface, said radiating element having a 60-degree triangle apex that is formed by the intersection of two linear triangle sides, and said radiating element having a linear triangle base at whose opposite ends said triangle sides terminate, said triangle base being located generally adjacent to said first edge;a linear metal feed line including and formed as an extension of said triangle apex, said feed line extending in a direction away from said triangle base and extending from said triangle apex toward said second substrate edge;a continuous metal ground plane element on said second surface, said ground plane element having a first edge located generally adjacent to said second substrate edge, and said ground plane element having a second edge that dimensionally overlaps said feed line and only said apex of said radiating element;electrical connection means having a ground element and a feed conductor;first connection means electrically connecting said ground element to said ground plane element; andsecond connection means electrically connecting said feed conductor to said feed line.
