1. A WiMAX segmented patch antenna with partial ground, comprising:
a substrate having a top side and a bottom side,
wherein the bottom side comprises a partial ground in the form of a metallic strip over which a coaxial feed is soldered,
wherein the top side comprises a conductive sheet disposed over the substrate, the conductive sheet comprising a main rectangular patch segment,
the main rectangular patch segment comprising:
a first slot, a second slot, a third slot, a first slit, a second slit, and 3 diodes,
wherein the diodes are connected across each of the slots,
wherein the first slit is connected to and perpendicular to the first slot and the second slit is connected to and perpendicular to the second slot, and
wherein the top side of the segmented patch antenna further comprises two rectangular parasitic elements each parasitic element further having an additional integrated diode,
wherein the segmented patch antenna is configurable to operate in 12 independent modes by turning on or off the diodes.
