A dual frequency cavity backed slot antenna and method of tuning the antenna, wherein the antenna comprises a plurality of stacked layers including a layer having a substrate with an accessible surface, the surface including thereon a continuous slot, first electrically conductive metallization disposed within the slot and extending to the slot, second electrically conductive metallization disposed external to the slot and at least one pair of frequency adjusting devices, one such device associated with the first metallization and the other device associated with the second metallization. The device pairs are either a foil and a tab, a pair of foils or a pair of indentations, one in each of the metallizations. <IMAGE> |
