Abstract

A low cost circular waveguide feed operates from 17.5 to 19.5 GHz with excellent radiation pattern symmetry, low cross polarization and low back radiation. The design consists of a circular waveguide open end with a quarter-wave choke and a pair of E-plane slots. A dielectric slab is employed to improve impedance matching. The feed is energized with a probe at the end of a coaxial cable instead of a conventional circular or rectangular waveguide. The cable introduces a small loss but significantly simplifies the design and reduces fabrication costs. [ABSTRACT FROM AUTHOR]
