This situation exists in particular when infants wearing anti-rapt tag take bath. This study discusses the effects on the electromagnetic radiation of an emitting tag plunged into a water volume and then proposes a statistical method to predict the radio coverage of the immersed tag. Finally it demonstrates that the RFID technology is barely affected by this issue even though other RFID technologies do not support immersion.","PeriodicalId":286017,"journal":{"name":"2014 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116949096","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}
