1. An antenna comprising:

  • a dielectric substrate layer;

    a patch layer comprising a conductive patch, said patch layer on top of said substrate layer;

    a 0°

    -90°

    hybrid chip;

    a proximity probe located on an external side of said antenna such that said proximity probe is not in contact with said conductive patch of said patch layer; and

    at least one additional external proximity probe located on said external side of said antenna such that said at least one additional proximity probe is not in contact with said conductive patch of said patch layer;

    wherein each said probe is vertical, comprised of conductive material, and in communication with said hybrid chip; and

    wherein said antenna is adapted to provide dual band coverage with a patch mode and a slot mode via said proximity probe.
