A comparative analysis of dual profile corrugated circular waveguide horns has been carried out. It comprises the radiation pattern, horn size and phase centre location and the variation over frequency. The analysis demonstrates interesting effects of the exponential section length on the horn performance, leading to optimised electrical behaviour combined with a minimum space occupation. The small variation of the phase centre with frequency looks promising in multiband applications. Results are validated by comparing E-plane and H-plane radiation diagrams with measurements.

Abstract
A comparative analysis of dual profile corrugated circular waveguide horns has been carried out. It comprises the radiation pattern, horn size and phase centre location and the variation over frequency. The analysis demonstrates interesting effects of the exponential section length on the horn performance, leading to optimised electrical behaviour combined with a minimum space occupation. The small variation of the phase centre with frequency looks promising in multiband applications. Results are validated by comparing E-plane and H-plane radiation diagrams with measurements.
