The unit cell of the proposed absorber is made up of two modified concentric circular rings printed on a grounded dielectric substrate. The surface power loss distribution on the unit cell confirms the dual-band nature. A planar absorber fabricated with 25x25 unit cells is tested for its absorption characteristics and found to exhibit more than 99% absorptivity at both 5.2 GHz and 10.4 GHz frequency bands. The proposed dual-band absorber maintains its absorptivity for various polarization angles and wide-angles of incidence.","PeriodicalId":216814,"journal":{"name":"2019 IEEE 5th Global Electromagnetic Compatibility Conference (GEMCCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128853887","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}
