In particular we analyze and quantify the power level of the third harmonic backscattered signals by the tags. The study shows the presence of a third harmonic signal for all tested UHF RFID tags, including tags equipped with the most recent chips. The measurement shows that the level of the radiated third harmonic signals is strong enough to be detected and potentially processed. In addition, if the radiated power of the third harmonic signal varies from one tag to another having the same chip and different antennas, this variation is minor considering identical tags.","PeriodicalId":212607,"journal":{"name":"2021 IEEE International Conference on RFID Technology and Applications (RFID-TA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130634401","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}

CMOS RF rectifiers enable miniaturization and improved integration with full systems. For certain applications, rectifiers may need to be deployed in high or low temperature environments, which can affect their power conversion efficiency (PCE). This work presents the design of a high efficiency 915 MHz CMOS Dickson charge-pump in a 2S nm FDSOI process, and investigates antenna-based impedance matching as a method of maximizing the PCE for different temperatures and CMOS process variations. With a co-designed antenna, the proposed rectifier achieves $ 5.4times $ higher PCE compared to simple inductive-matching at -20dBm. The PCE is then analyzed for CMOS process and temperature variations. It is shown that the rectifier can maintain 94% of its peak PCE at -15dBm at -10°C through input-impedance matching. The proposed rectifier and matching technique achieves the highest PCE compared to state-of-the-art Dickson multipliers, while having the smallest die area.","PeriodicalId":212607,"journal":{"name":"2021 IEEE International Conference on RFID Technology and Applications (RFID-TA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133810953","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}

Array of chipless RFID sensor tag for wireless detection of crack on large metallic surface 一种用于大型金属表面裂纹无线检测的无芯片RFID传感器标签阵列

A single sensor tag contains compass-shaped and a pair of L-shaped resonators. The metallic object under observation is identified by resonant frequencies of L-shaped resonators and crack on metallic object is observed by shift in resonant frequency of compass-shaped resonator. The unit cell tag provides read range of 120 cm and sensitivity of around 75 MHz/mm for 6 cm wide square-shaped surface. However, its performance degrades for larger surface. Therefore, a $3 times 3$ array of sensor tag is proposed for larger surface area. The $3 times 3$ array configuration can detect crack but can’t identify crack location due to the identical elements. To resolve the issue an idea of series array having five rectangular resonators with non-identical dimensions hence multiple resonant frequencies is presented. It helps to identify presence and position of crack on relatively large metallic surface.","PeriodicalId":212607,"journal":{"name":"2021 IEEE International Conference on RFID Technology and Applications (RFID-TA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129346953","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}

Therefore, RFID technology may be the solution to reduce down the time to monitor the workers and obtain the related information. UHF RFID technology has the advantage of reading from a farther distance beside the provision to store information about the tagged worker offering a better reliable solution for their traceability and safety. Here, a UHF RFID tag antenna is proposed to develop an “IoT enabled RFID system” for the monitoring of workers. The designed tag has a simple structure and does not require any metallic vias. The proposed tag exhibits a perfect conjugate match to that of the integrated Higgs-4 chip in the European band. The tag is first designed for free space and then optimized to work on a worker’s helmet with a read range of 4.6 meters.","PeriodicalId":212607,"journal":{"name":"2021 IEEE International Conference on RFID Technology and Applications (RFID-TA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127296715","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}
