Abstract

A novel slow-wave-structure (SWS) named angular log-periodic micro-strip meander-line was proposed in this paper. This kind of slow wave structure is mainly determined by 3 parameters only, and the calculation results show that it has a very weakly dispersion s. That is to say, its operation bandwidth would be very wide. Its another advantage is the low operation voltage. The radial normalized phase velocity by light velocity of wave can be as low as 0.04, while the DC voltage just 400 V, which is much smaller than conventional traveling wave tubes. The dispersion and transmission characteristics of this kind of slow wave structure were obtained.
