An Investigation of Open- and Short-Ended Resonators and Their Applications to Bandpass Filters Gao Le Dai; Xiu Yin Zhang; Chi Hou Chan; Quan Xue; Ming Yao Xia Microwave Theory and Techniques, IEEE Transactions on Volume 57, Issue 9, Date: Sept. 2009, Pages: 2203-2210 Digital Object Identifier 10.1109/TMTT.2009.2027173 Summary: In this paper, we investigate both open- and short-ended half-wavelength microstrip resonators and their applications to bandpass filter designs. Using voltage-wave analyses, we examine the resonance and coupling properties of these resonators at thei...
