This paper researches on the impact of structure accuracy of microwave filters on their electrical properties, in view of capacitive irises in rectangular waveguide and coaxial filters.First, the polygon discretion method is proposed, in which irregular waveguide patches are equivalent to discrete waveguide steps. At the same time, the mode-matching method is introduced to analysis

Modern microwave communication systems require high-performance filters having low insertion loss and high selectivity together with linear phase in its passband. Cross-coupled filters are able to accomplish these specifications by introducing the prescribed transmission zeros.Due to their good performances, cross-coupled filters are widely used in practice.This paper is mainly devoted to general coupling matrix synthesis
