Characterization of a dual-mode horn for submillimeter wavelengths

Abstract

A simple dual-mode conical horn has been developed and tested at 0.5 mm, 1.4 mm, 3.1 mm, and 34.2 mm. The horn has nearly equal beam shape in the E and H plane far field patterns with a 3dB half angle of 6°. At 34.2 mm the waveguide reflection loss and the phase center have been determined.
