Aperture-Coupling Effect Of Two-Layered Open-Loop Microstrip Bandpass Filters Designed By The Cul-De-Sac Coupling Matrix
international conference on electromagnetics in advanced applications(2019)
摘要
Planar-circuit filters based on the Cul-de-Sac coupling matrix is proposed by using square and hexagonal open-loop microstrip resonators. The resonators are arranged to be strongly coupled to the adjacent resonators. The filter is constituted by the two dielectric layers having a coupling apertures. Effectiveness of the proposed filter is investigated numerically and experimentally.
