NDLI: Generalised Chebyshev function bandpass filters in box-like topologies based on the properties of dual-mode loop microstrip resonator

Content Provider	IET Digital Library
Author	Liu, Qing Zhou, Dong Fang Zhang, De Wei
Abstract	A new class of compact microstrip bandpass filters in doublet topology based on a dual-mode loop microstrip resonator with controllable locations of input/output feeding lines is presented and researched. Filters with up to five poles are proposed and researched. Diagonal cross-coupling path in box-like topology can be introduced to produce a finite transmission zero (TZ) with controllable position. Some design examples are provided to illustrate the performances of the proposed two-, three-, four- and five-pole filters with controllable TZs. A three-pole and a five-pole filters were fabricated and measured. Good agreement is achieved between the simulated and the measured results.
