Dispersive surface antenna structures (300, 700) provide improved selectivity and increased control over bandwidth. Antenna structures (300, 700) include a wraparound piece of conductive material located perpendicular to a ground plane (304, 704). Ground posts (302, 702) extend up from the ground base (304) and capacitively couple to a front conductive surface (301, 701) of the antennas (300, 700). First and second conductive back surfaces (305, 306), (705, 706) are capacitively coupled across a gap (307, 707) along the back of the antennas (300, 700). The size, width, and location of the gap (307, 707) along with the ground posts (302, 702) provide increased control over antenna performance.
