Efficient computer design of compact planar band-pass filters using electrically short multiple coupled lines

摘要: The design of high performance, compact, planar band-pass filters using large numbers coupled, electrically short, microstrip transmission lines, with multiple non-nearest neighbor coupling, is presented. High order frequency dependent lumped elements are used to accurately represent the filter structure, including all intended or parasitic coupling. While generally applicable, this technique particularly useful for manufactured thin film Temperature Superconductors (HTS), where small size required.
