TY - JOUR A1 - Álvarez Melcón , Alejandro AU - Mosig, Juan Ramón AU - Guglielmi, Marco T1 - Efficient CAD of Boxed Microwave Circuits Based on Arbitrary Rectangular Elements Y1 - 1999 SN - 0018-9480 UR - http://hdl.handle.net/10317/3209 AB - 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 investi- gated, thus clearly demonstrating that the CAD tool developed can indeed be used very effectively for the design of a large variety of microwave circuits.
