Patent ID: 8456366

Claim:
A communications structure comprising: a ground plane; a ground conductor electrically coupled to the ground plane; a feed conductor; a first antenna branch electrically coupled to the ground conductor, wherein an electrical coupling between the first antenna branch and the ground conductor is spaced apart from an electrical coupling between the ground plane and the ground conductor; a second antenna branch electrically coupled to the feed conductor, wherein the first and second antenna branches are spaced apart; and an impedance matching line electrically coupled between the ground plane and the second antenna branch, wherein a segment of the impedance matching line is spaced apart from the ground conductor, wherein the feed conductor comprises an inner conductor of a coaxial RF feed structure, and wherein the ground conductor comprises an outer conductor of the coaxial RF feed structure so that a portion of the ground conductor surrounds a portion of the feed conductor, wherein the ground conductor and feed conductor are spaced apart from the ground plane.
