In this paper, the design and measurement results of the input coupling system for a W-band gyro-TWA is represented. The coupling system was designed to achieve 10% bandwidth centered at 95 GHz. In the measurement, an average transmission coefficient of -2.0 dB was measured over the designed frequency range.
