The proposal experimentally demonstrates the correct classification of different plastic materials based on their dielectric properties, dealing with large sources of uncertainty introduced by pellet measurements such as air gaps and position/dimension of the pellets. The proposed technique results attractive for the plastic industry as it involves a fast and nondestructive process along with the use of small circuit elements.","PeriodicalId":196456,"journal":{"name":"2021 96th ARFTG Microwave Measurement Conference (ARFTG)","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130348366","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}

The two antennas are modelled with the enclosure and all metallic parts of the reader, and simulated using a 3D EM simulator. The designed Folded IFA has dimensions of $0.1ast lambda 0 mathrm{x}0.1ast lambda 0$. Compared with the dimension of the actual PIFA $0.1ast lambda 0 mathrm{x}0.1ast lambda 0 mathrm{x}0.014ast lambda 0$, the proposed miniaturized antenna has better performance than the PIFA and can reduce the volume of the device up to 50%. The simulation results are validated by the measurements performed on the prototyped readers with the two antennas. The performances of the readers are evaluated with a developed test bench based on the ADALM-Pluto SDR platform and a Raspberry PI. The readers are also tested in a vehicle equipped with TPMS sensors.","PeriodicalId":196456,"journal":{"name":"2021 96th ARFTG Microwave Measurement Conference (ARFTG)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114899269","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}
