Patent ID: 7973720

Claim:
Antenna apparatus, comprising: a dielectric substrate comprising a plurality of surfaces; a ground plane; a first antenna element disposed at least partially on a first surface of the dielectric substrate and at least partially on a second surface of the dielectric substrate, the first antenna element configured to be coupled to the ground plane at a first location; a second antenna element disposed at least partially on a third surface of the dielectric substrate, the third surface and the first surface being disposed substantially at opposite ends of the substrate, and at least partially on the second surface, the second antenna element configured to be coupled to the ground plane at a second location; and an electromagnetic coupling element disposed substantially between the first element and the second element; wherein the first antenna element is configured to be galvanically coupled to a feed structure at a third location; and wherein the second antenna element is configured to be electromagnetically coupled to the feed structure through the electromagnetic coupling element so as to form a resonant structure between the first antenna element, the second antenna element, the dielectric substrate, and the ground plane.
