ABSTRACT:
An integrated multi-band and multi-polarization antenna array comprising: a plurality of first waveguides located in spaced parallel relationship, the waveguides being dimensioned so as to carry signals of a first wavelength, the waveguides containing slots in a first surface so as to radiate the signals carried by the first waveguides with horizontal polarization, a plurality of second waveguides located in spaced parallel relationship to each other and to the first waveguides, and bridging and abutting the first waveguides adjacent a second surface opposite the first surface, the second waveguides being dimensioned to carry signals of the first wavelength, the second waveguides containing slots in a surface parallel to the first surface so as to radiate signals carried by the second waveguides with vertical polarization, a third waveguide located in spaced parallel relationship to the first and second waveguides, dimensioned to carry signals of a second wavelength, and containing slots in a surface parallel to the first surface so as to radiate signals carried by the third waveguide with vertical polarization, the third waveguide being disposed between walls of the first waveguides and above a second waveguide at a location whereat electric field reflections from faces thereof of energy emitted from the second waveguide add in antiphase.
