The antenna array comprises four electrically small shorted patch antennas, and can switch the radiation patterns between vertical and horizontal modes. The antenna properties were examined by performing theoretical calculations and experiments. A fabricated antenna array on a printed circuit board is as small as 124 mm by 124 mm, and the measurements demonstrate that two radiation patterns of vertical and horizontal modes are obtainable. We believe that the antenna array should improve the usability of the IMES transmitter.","PeriodicalId":101990,"journal":{"name":"2016 IEEE/ACES International Conference on Wireless Information Technology and Systems (ICWITS) and Applied Computational Electromagnetics (ACES)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126446379","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}

In this study, the dielectric properties of dextrose solutions are investigated with an open ended slim form dielectric probe in order to identify the most suitable frequency of operation for an RF sensor. Measurement results showed that at 500 MHz the dextrose dependent dielectric property discrepancy is higher. However, the role of the error introduced during dielectric property calculations is not investigated yet. Therefore, the S parameter responses will be studied for further verification.","PeriodicalId":101990,"journal":{"name":"2016 IEEE/ACES International Conference on Wireless Information Technology and Systems (ICWITS) and Applied Computational Electromagnetics (ACES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130103889","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}
