Abstract
A Vlasov antenna (mode converter) for a center frequency of 220 GHz, which includes a Vlasov-type step-cut launcher and a parabolic reflector, is proposed in this paper. It converts the TE03 mode in circular waveguide to a highly Gaussian-like beam at the output window. Optimization is carried out and good results have been achieved with the VSWR 1.2 at 190-250GHz and the conversion efficiency greater than 80%. Simulation results showed that the radiation gain of the Gaussian-like beam is 31.8dB.
