Three combline resonators are employed, and the coupling between the adjacent and non-adjacent resonators are achieved by tuning varactors. It is shown that with the non-adjacent coupling path, two transmission zeroes at both sides of the passband (totally four) are present, and therefore the stopband rejection is significantly improved. This non-adjacent coupling also contributes one additional pole to the passband response. The positions of the transmission zeroes and passband bandwidth are controllable by changing the coupling values. A tunable filter at 640-1030 MHz is demonstrated with a controllable bandwidth of 8-12% and a wide stopband region. The application areas are in modern multi-standard communication systems.","PeriodicalId":128968,"journal":{"name":"2013 IEEE MTT-S International Microwave Symposium Digest (MTT)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121562491","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}

Recently, coil arrays have shown significant advantages over large single channel volume coils at ultra-high magnetic field strengths. However, to maximize the full potential, each individual coil within the array needs to be “tuned and matched” to the anatomy (load) prior to imaging. Tuning and matching can be a tedious and time consuming process, and has been cited as a problem that precludes ultra-high field strength MRI from a becoming a clinical reality. Here, we have developed an electromechanical solution. A 16-channel transmit-only TEM array was designed and fitted with piezoelectric actuators mechanically linked to sliding cylindrical tuning and matching capacitors to automate the tuning and matching process, based on the coil's reflection coefficient.","PeriodicalId":128968,"journal":{"name":"2013 IEEE MTT-S International Microwave Symposium Digest (MTT)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127947397","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}
