    Abstract

    A corrugated horn was design to achieve high Gaussian content horn and low reflection over an operating frequency range of 90-100 GHz was designed and verified by measurement with a vector network analyzer (VNA). The corrugated horn will be used in a W-band gyro-TWA experiment to convert TE11 mode in circular waveguide into a Gaussian-like HE11 mode. The measurement shows a lower than -30 dB reflection over the desired frequency range, and the Gaussian percentage is about 99.4%, which is close to the simulation results.
