The numerical analyses showed that the former can give better results of quality factor (QF) and self-resonant frequency (SRF) and the L value of the former can satisfied the nH level requirements where the Q factor obtains its highest value. Experimental results showed that the former can gives a 50.5% increase for the maximum Q value and 164.5% increase for the SRF whereas the latter can supply over 3 times larger L value. The simulation results have good agreements with the theoretical analyses. At last the design guidelines were given according to the simulation and experimental results.","PeriodicalId":113164,"journal":{"name":"2006 7th International Symposium on Antennas, Propagation & EM Theory","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123493173","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}

In second step, the three-dimensional (3-D) Vector-FEM is used to model the inhomogeneous structure of the circulator, and FEM field are matched with the field of microstrip at the 3 interfaces. So a sparse matrix equation is obtained, and it is solved with the SSOR-BICG algorithm. Numerical results of the circulator are presented and compared when the ferrite disk radius changed.
