It is important to characterize dielectric properties of material so that the performance of the devices can be predicted accurately. There are numerous dielectric characterization methods and each of the methods have its own benefits and limitations. In this work, a simple complementary double split ring resonator operating at 3.5 GHz is proposed for dielectric measurement. The advantage of this design is the convenience in preparation of samples. Empirical models are proposed to predict the relative permittivity and relative permeability of material under test. The reliability of the mathematical equations is proven from its R2 and RMSE values.","PeriodicalId":177263,"journal":{"name":"2021 IEEE Asia-Pacific Conference on Applied Electromagnetics (APACE)","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127363345","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}

The loading effect of four ring slots stimulates a hybrid mode in the cylindrical cavity that generates eight magnetic monopoles with high gain in boresight. Through controlling the phase difference between the two ports, six types of polarization can be demonstrated. Simulation results in 28 GHz show a maximum gain of 13 dBi, 10% bandwidth, and a good cross-polarization level in all polarization states. Distinct features including low-profile, low-cost, single-layer, and simple feeding network make the antenna a suitable candidate for upcoming millimeter-wave and 5G applications.","PeriodicalId":177263,"journal":{"name":"2021 IEEE Asia-Pacific Conference on Applied Electromagnetics (APACE)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124206131","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}
