ABSTRACT:
A slot antenna is provided which includes first and second oppositely disposed metallic plates with a dielectric layer disposed therebetween. An array of horizontal and vertical radiating elements are formed on the first metallic plate. An array of horizontal coupling slots and an array of vertical coupling slots are formed in the second metallic plate. The antenna further includes first and second beam formers for providing a necessary field of view beam coverage. The array of horizontal coupling slots are operatively coupled to the first beam former and the array of vertical coupling slots are operatively coupled to the second beam former. Accordingly, the slot antenna may operate to transmit and receive linearly polarized energy. The antenna may further include a polarizer disposed above the upper metallic plate for converting between linear and circular polarization so as to allow for antenna operation with single or dual circular polarization energy.
