This paper presents the optimum selection of helix tape parameters for the design of Ku-band 140W short length TWT for space communication application. CST MWS code and in-house developed SUNRAY-3D codes have been used to design helical slow wave structure. In this model, helix is considered as perfectly conducting tape. The dependency of gain flatness and gain per unit length on tape thickness, tape width and helix pitch have been studied by maintaining the propagation constant(β) fixed at central frequency(i.e. 11.3GHz). Dependency of interaction impedance on helix tape width and tape thickness has also been studied.
