In all these cases, the ergonomics of the physical reading process can be hindered if read range requires a user to awkwardly maneuver the tag near the reader until a read is achieved. One way to facilitate an extended and reliable read range borrows on knowledge from the wireless power transfer community where it is known that increasing the Quality factor of the reader or tag coil will increase power transfer. However, RFID engineers have typically limited maximum coil Q factor to about 10-20 due to the need for maintaining a system bandwidth that is broad enough to support the necessary communication data rates. To meet this challenge, this paper introduces a method of impedance matching high Q reader coils to the source known as \"over-coupling\" the source to the system input. On one hand, the use of high Q coils extends the range where the tag receives sufficient power to turn on, while it is over-coupling that slightly damps the system resonance, producing an effective system Q factor that simultaneously supports a bandwidth wide enough to accommodate necessary data rates. This work will show both theoretically and through experimentation that using high Q coils in the over-coupled regime supports extension of read range in near field RFID systems by 81% or more compared to the next best impedance matching strategies.","PeriodicalId":105916,"journal":{"name":"2016 IEEE International Conference on RFID (RFID)","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124923369","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 passive tag antenna has two separable parts, which are the feeding loop and the radiating element implemented at two different layers. Energy is efficiently coupled between these two parts when they overlap within designated positions. For demonstration purpose, the overall tag design is realized on a card (credit card size), and a card-holder, with the feeding loop embedded in the card and with the radiating element embedded in the card-holder. The key features of the tag design are i) the intended short read range of millimeter-to centimeter-level when the card is stand alone, and ii) the regular long read range of meter-level when the card is coupled with the card holder. With this distinctive characteristic, a card with a unique tag ID can be issued to a single person, on a one-to-one basis, for different read range access requirements in different situations, e.g. office gate access vs car park gate access of a single person to go in and out of a premises using the same access card, nearfield payment vs road toll payment using the same payment card. Therefore, unnecessary false-read can be minimized and no multiple cards (different tag IDs), with different read ranges, are needed for the same person. A PCT patent of such design has been filed in Sept 2015 for licensing. A few hundred of proof-of-concept prototypes have been fabricated recently for field trials.","PeriodicalId":105916,"journal":{"name":"2016 IEEE International Conference on RFID (RFID)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125320622","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}

Hussain, Songfan Li, Li Lu","doi":"10.1109/RFID.2016.7488004","DOIUrl":"https://doi.org/10.1109/RFID.2016.7488004","url":null,"abstract":"In recent years, Computational RFID tags (CRFIDs) have emerged as viable software-defined platform for academic research and experimentation. In addition to EPC protocol, these tags perform sensing and computation through power scavenging. However, existing CRFIDs are pre-programmed to execute a specific firmware whereas programming tools comprising wired interface and PC-based software are required to erase, modify or reprogram the tag. Such limitation demands an over-the-air (OTA) scheme which can wirelessly upgrade or reprogram the CRFID tags while following the EPC protocol. We present the design, implementation and evaluation of R2 - the first OTA reprogramming scheme for CRFID tags without requiring any modification to EPC protocol, or an upgrade to RFID reader or CRFID tag. We develop a User Interface and realize our scheme on three platforms which include both software-defined as well as chip-based CRFIDs, i.e., WISP5.1 and Optimized WISP (Opt-WISP), and Spider tag. It also includes both the FLASH and FRAM based micro-controller memories. We evaluate our scheme from three aspects: time and energy overhead for reprogramming operation itself; overall system delay to verify the compatibility of R2 with EPC protocol; success rate in line with interrogation range. We foresee our endeavour to offer viability of OTA reprogramming and upgrade for CRFID systems.","PeriodicalId":105916,"journal":{"name":"2016 IEEE International Conference on RFID (RFID)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122790700","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}
