ABSTRACT:
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 tabs, one tab coupled to the first metallization and the other tab coupled to the second metallization. The tabs are electrically conductive metallization, the tab coupled to said first metallization extending outwardly toward the second metallization and the tab coupled to the second metallization extending inwardly toward the first metallization. A slot is provided between the tab coupled to the second metallization and the second metallization. Each tab of a pair is coaxial with the other tab of the pair and symmetrical about the axis. Plural pairs of tabs can be symmetrically disposed about the slot. The antenna is tuned by decreasing the area of at least one of the pair of tabs to alter at least one of the resonant frequencies of the antenna.
