Multi-Element Cavity-Coupled Antenna

A window (12) having an integrated antenna (10), said window (12) comprising:

• a nonconductive pane (16) of transparent material;
• a patch element (18) formed of conductive material and disposed adjacent said non-conductive pane (16);
• a coupling element (20) formed of conductive material and having an interior edge (22) defining a cavity (24), said coupling element (20) disposed non-planar with and generally parallel to said patch element (18);
• a plurality of radiating strips (26) formed of conductive material and arranged as at least two dipole pairs in a crossed-dipole pattern and disposed non-planar with and generally parallel to said patch element (18);
• said radiating strips (26) disposed within said interior edge (22) of said coupling element (20);
• a first dielectric layer (38) formed of a non-conductive material and sandwiched between said patch element (18) and both said radiating strips (26) and said coupling element (20);
• and
• a ground plane (36) formed of a conductive material and disposed non-planar to and generally parallel with said radiating strips (26) and opposite said patch element (18).
