The innovative concept of the slow-wave microstrip lines on MnM-substrate is presented, as well as the electromagnetic considerations, fabrication process, and measurement results. Initial results show high relative dielectric constants (up to 43). Hence, it is possible to reach high-quality factor transmission lines within a great range of impedances, from 20 to 100 Ω, without critical dimensions.","PeriodicalId":262816,"journal":{"name":"2014 IEEE MTT-S International Microwave Symposium (IMS2014)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116743465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their responses can be reconfigured between all pass and tunable bandstop filter responses by simply tuning the center frequency of their resonators, avoiding insertion loss and control voltages associated with the series switches required in conventional bandstop filter banks that have similar response reconfiguration capability. In contrast to previously shown intrinsically-switchable bandstop filters, the filters shown in this paper require only one tuning element per resonator, have a significantly higher quality factor (650), and use electrically-short resonators. When combined with destructive interference attenuation enhancement techniques, these characteristics enable >60 dB maximum attenuation in the bandstop state and less than 2.0 dB insertion loss in the all pass state.","PeriodicalId":262816,"journal":{"name":"2014 IEEE MTT-S International Microwave Symposium (IMS2014)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114291631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
