Synthesis and properties of the surface impedance in the parabolic reflector antennas with low cross-polarization

Abstract

The use of the anisotropic reactive reflector is to eliminate cross-polarization is considered for the following two cases: a parabolic antenna fed by a dipole; and a parabolic antenna fed by a source radiating symmetrical E/sub 01/ or H/sub 01/ circular waveguide modes. The reflector surface impedance properties and design features typical for feed examples are discussed.<>
