Abstract
A stacked patch antenna comprises two or more patch antennas physically disposed in a stack to provide a multi-frequency or broad band antenna. However, independence of the resonant response frequencies of the lower and upper patches of each stacked patch antenna pair ground requires metallization dimensions for the upper patch's lower surface be contained within the perimeter of the lower patch's resonant metallization. Accordingly, composite stacked patch element dimensions are limited by the desired resonant frequency of the lower patch. The inventors have established an alternate physical structure where the resonant patch geometry of the lower patch element's upper metallization is not limited by the lower surface ground plane metallization of the first upper patch element. The inventors have also established design solutions allowing the lower frequency performance of the first, lower patch within a stacked patch antenna to be lowered without compromising footprint of the resulting antenna.
