Js. Row et Kl. Wong, RESONANCE IN A SUPERSTRATE-LOADED RECTANGULAR MICROSTRIP STRUCTURE, IEEE transactions on microwave theory and techniques, 41(8), 1993, pp. 1349-1355
The complex resonant frequency of a superstrate-loaded rectangular mic
rostrip structure is investigated. The study is performed by using a f
ull-wave analysis and Galerkin's moment method. The numerical converge
nce using sinusoidal basis functions, with and without considering the
edge singularity to expand the unknown surface current distribution o
n the rectangular patch, is discussed. Numerical results for the effec
ts of superstrate permittivity and thickness on the complex resonant f
requency of the rectangular microstrip structure are also presented.
