ABSTRACT:
A dielectric slab polarizer employs a unique configuration which provides improved impedance matching of the polarizer to the empty space of a waveguide section and, thereby, allows an approximate ninety degree differential phase shift transformation of RF field polarization to be achieved over a wider frequency bandwidth than heretofore attainable. The novel configuration of the slab polarizer is embodied by a flat middle section, conical tapered opposite end sections and reverse tapered intermediate sections which merge with the flat middle section and opposite end sections. The regions of merger between the respective intermediate sections and opposite end sections have a thickness greater than that of the middle section.
