Abstract

A slotted waveguide array configuration for the radiation of dual polarizations is described. The broadboard waveguide design considered consists of two interleaved slotted waveguides with longitudinal and transverse slots, respectively. Phase steering in the direction perpendicular to the waveguides is possible within a limited sector depending on the waveguide dimensions. Both polarizations are radiated from a common aperture, resulting in excellent polarization purity.<>
