摘要

In this paper, a W-band mode converter is designed using a circular corrugatedhorn and its detailed numerical study is presented. The proposed mode converterwas fabricated, and the measured results are validated. The device convertsfundamental mode (TE_(11)) into a Hybrid mode (HE_(11)) mode in afrequency range of 75 GHz to 105 GHz. The reflection coefficient is less than−15 dB and a peak directivity of 24.5 dB is achieved. The corrugated horn alsoshows good mode purity. The measured gain of the device was found to be18.05 dB. The designed mode converter will be useful in Electron CyclotronResonance Heating system for fusion plasma experiments.
