This paper presents novel types of polarizers that are composed of grooved circular waveguides. The presented polarizers are suitable for realizing high-performance and low-fabrication cost in the Ka-band and above because of simple structure. Accurate analysis and design of the polarizers are performed using full-wave mode-matching techniques applied to the circular-to-rectangular waveguide T-junctions and cross-junctions. Ka-band grooved circular waveguide polarizers fabricated with the aid of the analysis and design techniques have realized excellent performance without tuning elements.
