GLOBAL MODELING OF A PERIODIC COPLANAR WAVEGUIDE STRUCTURE FOR FILTER APPLICATIONS USING AN EFFICIENT ITERATIVE PROCEDURE

摘要

A global modelizing of periodic structures for coplanar waveguide filter is presented. These structures offer a very low insertion loss; thus, they can be exploited to achieve a high performance in miniature microwave filters. The analysis is achieved by using a new iterative method based on the wave concept. In this method, a recursive relationship between a given source and reflected waves from the circuit plane is generated. The good agreement between simulated and experimental published data justifies the design procedure.
