A Novel Class of High Selectivity Filters and Duplexers in Microstrip Technology

This article describes a novel configuration for high selectivity bandpass filters and duplexers in microstrip technology. The structure proposed is made of single-sided filters, which are characterized by requirements in one passband and one stopband,...
Modern communication systems often require narrow band filters presenting high selectivity and low insertion loss. When there are also stringent requirements on the overall dimensions of the filtering structure, it could become very problematic to select a suitable class of resonators having at the same time compactness and large...
