According to our implementation, a first mobile telephone transmits a quasi-continuous Bluetooth advertizing signal and the transponder scatters and modulates this signal such that it is receivable by a Bluetooth receiver of a further mobile telephone. The scattering process includes 4 MHz frequency translation and frequency shift keying for information transmission. The modulation process is controlled by a low energy micro-controller, which obtains its operational energy from a RF harvesting circuit that accumulates energy from the incident RF signals. The low energy transfer of Bluetooth signals motivates the present feasibility study, which proposes a supplement of WLAN signals as additional source of energy for the battery-less transponder. The present study includes examining alternative WLAN modes: ”tethering”, ”WiFi direct” and ”ad hoc” and concludes that an Android specific form of WLAN tethering shows the most promising potential for our scattering application, which is based on regular, unmodified mobile telephones. Thus, by additionally using WLAN signals, we achieved a significant range improvement of the wireless energy transfer from the transmitting mobile telephone to the battery-less transponder, which encourages further endeavors in this direction.","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":"120985708","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 T2T communication system is performed directly between a reader tag (RT) and a listener tag (LT) in the presence of an external electromagnetic (EM) field. Consequently, this kind of communication system implies the use of low RF signal levels, which makes it very sensitive to the noise, to the arrangement between the tags (i.e. spacing, tilt and shift) but also to the position of the source. The performance evaluation of this communication system is based on the study of the modulation depth, an indicator of the separation between the two modulation states and, indirectly, of the T2T communication quality. Considering scenarios in which the two tags are in the same plane but with the RT tilted and staggered with respect to the LT, our study demonstrates that the modulation depth can be kept higher for different separations between the tags by choosing the proper angle of incidence of the RF source with respect to the tag’s plane. The proposed approach is studied through electromagnetic simulations and the obtained results are confronted with measurements.","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":"127554176","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}

Radio Frequency Identification (RFID) antenna has been designed for global microwave bands, i.e., 2.4 GHz and 5.8 GHz for wearable wireless applications. To achieve circular polarization, traditional truncated opposite corners of the patch are introduced, resulting in an orthogonal electric field in the X and Y direction. Another truncated square slot patch miniaturizes the antenna, provides a dual band frequency response and the patch is finally placed on flexible wearable dielectric material. The Defective Ground Structure (DGS) is used to enhance the designed antenna's gain and bandwidth. The simulation result shows the radiated gain of 6.5 dBi at 2.4 GHz and 10dBi at 5.8 GHz. For better impedance matching, the return loss (S11) of −19.5 dB at 2.4 GHz and −45 dB at 5.8 GHz is achieved. The antenna is circularly polarized with an axial ratio bandwidth below 3dB for the wide range reading of RFID tags. The designed antenna provides better isolation to the Electromagnetic Interference (EMI) caused due to adjacent frequencies since it radiates at two frequencies only.","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":"121525298","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}
