The isolation technique is based on multiple electromagnetic band gap (EBG) cells loaded in the feed region of the two antennas. Proposed technique of isolation enhancement is highly compact as it does not impact the over-all antenna size and is exhibited in UWB-Narrow band antenna pair hosted on the same substrate. Apart from the antenna impedance and radiation characterization, envelope correlation co-efficient and diversity gain of the system is studied, revealing excellent results. The obtained isolation between the two antenna elements is better than 30 dB over the entire TJWB spectrum. Proposed isolation enhancement technique is radiator independent and can be used for other printed MIMO antennas also.","PeriodicalId":168839,"journal":{"name":"2015 IEEE Applied Electromagnetics Conference (AEMC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123770013","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}
