G. Mazzarella et G. Montisci, A rigorous analysis of dielectric-covered narrow longitudinal shunt slots with finite wall thickness, ELECTROMAGN, 19(5), 1999, pp. 407-418
The need for a protective dielectric cover is becoming more relevant in wav
eguide slot arrays, especially in space applications. The aim of this paper
is to describe a rigorous Method of Moment approach to the analysis of a d
ielectric-covered longitudinal shunt slot, taking into account the effect o
f the wall thickness. The whole procedure has been devised aiming at a time
effective but precise way to compute the slot admittance, tailored to the
needs of design procedures for slot arrays.
Simulated results are compared with experimental data, resulting in a very
good agreement.
