K. and Ahmad, B. H. and Shairi, N. A. and Wong, P. W.}, abstract = {This paper demonstrates a reconfigurable dual-mode ring resonator matched bandstop filter. The dual-mode ring resonator structure is composed by two degenerate modes or splitting resonant frequencies using a perturbing stub. The reconfigurable dual-mode ring resonator matched bandstop filter is realized by using PIN diodes as switching elements. This reconfigurable filter provides two states of operation; allpass and bandstop response. Frequency of 1 GHz is chosen to demonstrate this operation. The theoretical analysis together with simulation and measurement results are presented in this paper. As a result, this filter can be reconfigured between allpass and bandstop using PIN diodes at 1 GHz. {\^A}{\copyright} 2012 IEEE.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84873144014&doi=10.1109\%2fISWTA.2012.6373880&partnerID=40&md5=2e35df44091948c8012d8dab755f3434} }
