1. An antenna comprising:

  • a dielectric substrate comprising a plurality of surfaces;

    a first antenna element disposed at least partially on a first surface of said substrate and at least partially on a second surface of said substrate, the first antenna element adapted to be coupled to a feed structure at a first location and to a ground plane at a second location;

    a second antenna element disposed at least partially on a third surface of said substrate, the third surface substantially opposing the first surface, and at least partially on the second surface, the second antenna element adapted to couple to the ground plane at least at a third location; and

    an electromagnetic coupling element disposed substantially between the first element and the second element, and configured to electromagnetically couple the second antenna to the first antenna element so as to form a resonant structure between the first antenna element, the second antenna element, the dielectric substrate, and the ground plane.
