新型开环谐振器带通滤波器的设计_江新华（A new open-loop resonator bandpass filter design _ Jiang Xinhua） Fourteenth volume, third issue June 2008 Journal of Shanghai Univer (NATURAL SCIENCE EDITION) JOURNAL OF SHANGHAIUNIVERSITY (NATURAL SCIENCE) Vo.l 14 No. 3 Jun. 2008 Received: 2007-04-03 communication Author: Li Guohui (1970~), male, associate professor, doctor, research direction for microwave photonics and nonlinear theory. E-mai:l ghlee@ sohu. com Article number: 1007-2861 (2008) 03-0236-03 Research Brief Design of a novel open loop resonator bandpass filter Jiang Xinhua, Li Guohui (School of communication and information engineering, Shanghai Univer, Shanghai 200072) Abstract: a new class of square open-loop resonators with microstrip resonators designed by this new type of resonator can effectively reduce the filter A miniaturized bandpass filter is designed and fabricated by using one of the new resonators. The simulation and test results show that the filter is very good Frequency selectivity, stopband characteristics and smaller size. Compared with the conventional open-loop resonant filter, the size is reduced by 30%. Key words: miniaturization; bandpass filter; open loop resonator; microstrip line CLC number: TN 713+. 5, document identifier code: A Design, ofBand-Pass, Filter, with, NovelOpen-Loop, Resonators JIANG, Xin-hua, LIGuo-hui (School, ofCommunication, and, Information, Engineering, ShanghaiUniversity, Shanghai, 200072, China) Abstract:In, this, paper, several, square, open-loop, resonators, with, transmission,, lines, are, proposed, to Design, optimized, bandpass, filters., In, comparisonwith, conventional, open-loop,, resonator, bandpass, filters, The, proposed, filter, can, achieve, reduction., A, size, compactmicrostrip, filter, using,, one, of, these, open-loop Resonators, is, fabricated, and, measured., Simulation, and, measurement, on, the,, fabricated, filter, show, high- Frequency, selectivity, and, good, stop-band, characteristic, with, small,, dimensions
