Abstract
Dispersive surface antenna structures ( ) provide improved selectivity and increased control over bandwidth. Antenna structures ( ) include a wraparound piece of conductive material located perpendicular to a ground plane ( ). Ground posts ( ) extend up from the ground base ( ) and capacitively couple to a front conductive surface ( ) of the antennas ( ). First and second conductive back surfaces ( ), ( ) are capacitively coupled across a gap ( ) along the back of the antennas ( ). The size, width, and location of the gap ( ) along with the ground posts ( ) provide increased control over antenna performance.
