Improved Vlasov antenna with curved cuts for high power microwaves

This paper presents an improved Vlasov antenna with a novel cut shape suitable for high power microwave applications. The curved shape of the proposed cut totally eliminates the sharp edges and angles present in Vlasov antennas with Step and Bevel cuts. A Vlasov antenna, designed for operation at 3 GHz, is used to compare the three cut types. In addition to being better suitable for high power microwave applications, the proposed cut results in increased antenna gain and in good performance in terms of sidelobe level and half-power beamwidth.
