2021 IEEE International Conference on RFID Technology and Applications (RFID-TA) Pub Date : 2021-10-06 DOI: 10.1109/RFID-TA53372.2021.9617273

The decoupling principle is based on a weak field created by a T-shaped feeding line (TSFL) and the antenna element itself. When arranging another identical antenna in the weak field, high isolation between two antennas can be achieved without adding extra decoupling structure. First, the weak field of a single antenna is described and analyzed by the equivalent circuit. Then, the adjacent antenna is placed in the weak field to obtain a high isolation level of 51 dB between two-element MIMO antennas. Furthermore, a four-antenna linear MIMO was designed, which also achieved high isolation. With the merits of simple structure and efficient decoupling, these self-decoupling antennas are promising for MIMO UHF RFID Systems.","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":"133724877","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}

It is shown experimentally and theoretically that the backscattered complex signal, i.e. magnitude and phase, changes significantly with respect to the incident power at the tag’s antenna. This effect is neglected in prior art and is due to the change of the input impedance of the tag’s front end, due to the presence of non-linear components, like the rectifier’s diodes. Measured deviation of 14dBs and phase shift of 100 degrees is reported herein. These variations might lead to large localization errors, depending on the method and the measured quantity, unless the localization algorithm accounts for the expected variability.","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":"122109552","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 tag-to-tag link requires presence of excitation signal, either as a dedicated continuous wave exciter or an ambient RF signal. However, the link suffers from the limited range. The capability of RF tags to passively estimate the amplitude and phase of the wireless channel between pairs of communicating tags empowers these passive tags to provide a real-time, precise, fine-grained RF fingerprint of the environment. The phase estimation also enables collaboration between neighboring tags in order to improve the range and robustness of tag-to-tag link itself. We propose strategies that through the use of optimal collaborative reflection and backscatter of a cluster of tags improve the link range. We demonstrate that a single tag on a distance of 16 cm from the transmitting tag with optimal collaborative reflection improves the link range by 40%.","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":"129608235","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}

With this preliminary version of the music player textile, it is possible to play drum and piano.
