The same pattern has been adopted in the compact microstrip mushroom-like resonator (CMMR) as reported previously and here is applied to CPW. When compared with CMMR, the new structure has advantages of easy fabrication and low cost due to its single-layer configuration. To investigate the CMMR deeply, the effect of structural parameters, including patch size and diameter of via, on bandgap characteristics are analyzed in detail. Also, the 1-D CCMR EBG filter is studied for various numbers of cells. Finally, the wideband CCMR EBG filter using united cells method (UCM) is designed, fabricated, and measured. The correction and validity are confirmed by the results of simulation and experiment.","PeriodicalId":211786,"journal":{"name":"2010 International Symposium on Signals, Systems and Electronics","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132480272","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}
