The difficulties of using planar technology for microwave filters are discussed and the main design problems are presented with some solutions especially for the multi-passband filters. Some new dual passband filters are designed in this thesis. The suggested designs were developed and validated experimentally. The suggested dual-band filters are also published in international articles and journalsenFilter designFabricationGeometric analysisThesis
