摘要：
New quasi-lumped resonator bandpass filters with cross couplings are presented. Coaxial and suspended stripline structures are considered. These filters are notable for their extremely wide and deep upper stopbands at small dimensions. They also have transmission zeros near the passband that significantly improve frequency selectivity. Photographs and measured frequency responses for the four fabricated filters are presented. (C) 2014 Wiley Periodicals, Inc.
