Abstract
In this paper, we describe a very accurate and
computationally efficient computer-aided design (CAD) tool for
the analysis and design of a wide class of boxed microwave
circuits composed of arbitrary rectangular elements printed on
dielectric layers. The theoretical derivations are based on an
integral equation formulation, and call for the evaluation of the
boxed multilayer Green’s functions, thus leading to a tool that is
valid for an arbitrary number of circuits and dielectric layers.
In addition to theory, comparisons with measured results are
presented, and several practical filter structures are also investigated,
thus clearly demonstrating that the CAD tool developed
can indeed be used very effectively for the design of a large
variety of microwave circuits.
