It consists of an E-shaped coaxial-fed microstrip antennas operating at 958MHz and 2.35GHz each placed on all sides of a cube.

The dual loop antenna is consisting of two loop antennas connected in parallel to the rectifier circuit. Although the dual loop antenna has the same inductance as the small loop antenna, it has approximately 4 times loop length than that of the small loop antenna. Due to larger size, antenna gain of the dual loop antenna is higher than that of the small loop antenna. This can make higher rectification efficiency including antenna gain. The basis of the rectenna can be confirmed with simulational and experimental investigations.","PeriodicalId":162908,"journal":{"name":"2019 IEEE Asia-Pacific Microwave Conference (APMC)","volume":"255 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123347991","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}
