Abstract
A stacked patch antenna has a first element having a feed thereto spaced above a ground plane and one or more spaced apart parasitic elements spaced above the first element. The first and parasitic elements may be tuned to a fundamental mode for radiation of a specified frequency. The geometric centers of the parasitic elements are offset from one another and from the geometric center of the first element along the same direction. The stacked patch configuration provides increased gain and bandwidth. The offset configuration determines the direction of maximum gain for the antenna. The first and parasitic elements can be single antenna elements and may be microstrip antenna elements. The elements can also be arrays of microstrip antenna elements. The phasing of the arrays of microstrip elements can be controlled to determine a gain sensitivity direction.
