Therefore, this antenna can be applied for kinds of wireless communications in L band and S band with unidirectional radiations. Simulated realized gain at the 3 states of antenna height in their operating frequency bands are respectively greater than 6 dB (H=271 mm), 8.5 dB (H=147 mm) and 5 dB (H=57 mm). Right-hand circular polarization happens at state 2 from 2.04 GHz to 3.56 GHz (fractional circular polarization bandwidth=54%), and the CP bandwidth is better than the standard monofilar and previously proposed origami conical spiral antenna, while polarizations at the other 2 states are either linear or elliptical in their operating frequency bands.","PeriodicalId":6496,"journal":{"name":"2016 IEEE International Symposium on Antennas and Propagation (APSURSI)","volume":"96 1","pages":"839-840"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74682060","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}
