Abstract

A W-band corrugated horn incorporating a broadband vacuum window for use in a gyro-device as a quasi-optical launcher has been designed, manufactured and experimentally measured. This horn, including a 3 disk vacuum window, converts a cylindrical TE11 mode into the free space TEM00 mode over the frequency band of 90-100 GHz with a reflection better than -30 dB and a coupling efficiency of ∼99.4%.
