Full-wave analysis of dielectric-covered radiating series slots

The need for a protective dielectric cover is presently more and more relev ant in waveguide slot arrays, especially in space applications. Therefore, the knowledge about waveguide slot arrays radiating into free space must be completed to design dielectric-covered arrays. The aim of this paper is to describe a rigorous method-of-moment approach to the analysis of a dieletr ic-covered inclined series slot, able to take into account the effect of th e wall thickness. The whole procedure has been devised aiming at a time-eff ective but precise way to compute the slot resistance, tailored to the need s of slot array design procedures.
