Cold-test characteristics simulation of a v-type microstrip meander-line slow wave structure

In this paper, a novel v-type microstrip meander-line slow wave structure (MMSWS) is presented. With the electromagnetic simulation software HFSS, the comparisons of the dispersion characteristic and coupling impedance between the novel and traditional MMSWS are given. Then the cold-test characteristics of the v-type structure for different parameters are calculated. Also, the structure supported by dielectric slab is analyzed. The results demonstrate that the v-type structure has a better performance than the traditional in both bandwidth and coupling impedance, while the structure supported by dielectric slab has an even better performance than the former.
