An EM-Based Cascade Design Procedure for High-Order Bandpass Filter

In this paper, a cascade design procedure exploiting segmented approach and the space mapping technique is proposed for efficient EM-based design optimization of high order microwave bandpass filters. The theory of the proposed method is discussed in detail. The optimization routine is presented. A ten pole hairpin microstrip filter is optimized efficiently using Keysight ADS and Sonnet EM simulator to validate the proposed method.
