Propagation characteristics of corrugated substrate integrated waveguide with no metallic vias

Abstract
In this paper, a corrugated substrate integrated waveguide (CSIW) with no metallic vias is proposed, and its propagation characteristics are investigated via our numerical SOC de-embedding method. In our analysis, dominant operating modes in this CSIW at different frequencies are extensively discussed. In final, its complex propagation constant, i.e., phase and attenuation constants, is derived to demonstrate its frequency-dispersive transmission and attenuation performance.
