Indeed, tagged items (either static or randomly moving in the scenario) that are close to the reader antenna could be detected even if they are not on the conveyor (false positive readings). The classification procedure here proposed is based on some features that are extracted from a phase-based technique used to localize tags on a conveyor belt, which takes advantage of the fact that the tagged items move along a conveyor whose speed and path are both known a priori. Differently from other techniques that are used to solve the above misclassification issue, the proposed approach does not require multiple antennas.","PeriodicalId":143130,"journal":{"name":"2014 IEEE RFID Technology and Applications Conference (RFID-TA)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116777767","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 design of a UWB antenna for application in smart textiles is very challenging. For end users, the antenna should be unobtrusively integrated into smart textile and comfortable to wear. From a system point of view, good impedance matching and radiation characteristics over a very large bandwidth are of major importance, even under harsh operating conditions. Our approach consists of applying copper tube eyelets to implement a cavity-backed slot antenna in textile materials. A prototype was realized and measured. The measured return loss characteristic and radiation performance after bending and deploying the antenna on different human body parts prove that our antenna is extremely suited for on-body use. A -10 dB-bandwidth of 1.33 GHz, or 33 %, was realized, in which the radiation pattern remains quasi invariable.","PeriodicalId":143130,"journal":{"name":"2014 IEEE RFID Technology and Applications Conference (RFID-TA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130167168","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 design consists of two single series rectifier circuits that add the currents from each diode, in order to increase the offered power at the load. Despite the fact that a lossy and low-cost FR-4 substrate was used, the rectenna-grid offers 200 μW at load for 1 μW=cm2 ambient power density, while for 0.01 μW=cm2 the power at load reaches 0.8 μW. Furthermore, RF-to-DC rectification efficiency of 20.5% and 35.3% is achieved at -20 and -10 dBm power input, respectively. Measurements of the proposed RF harvester agree well with simulations. Finally, the rectenna was connected to a DC-to-DC converter and the open voltage was increased from 298 mV to 1.4 V, charging a 1 mF capacitor at 37 min.

The reader described in this paper has been developed to facilitate the localization of the so-called Smart Pebbles, i.e. real pebbles taken from the beach under study and provided with an embedded RFID transponder, then positioned on and under the seabed. The developed device is able to detect the presence of a Smart Pebble up to a 50cm distance, and its functioning has been tested at depths up to 5 meters for prolonged spans of time (up to 4 hours).

It offers contactless communication, non line-of-sight readability, compactness, and low cost. Localization techniques and algorithms have been actively researched recently from accuracy point of view. However, less attention has been paid to the antenna and its effects on the achieved localization accuracy. Particularly, wearable antennas in human localization applications are key components affecting the achieved accuracy and reliability. In this paper, we elaborate on the material choice for wearable UHF RFID patch antennas. Two highly attractive and flexible conductive electro-textiles are discussed and compared: anisotropic embroidered textile structure and uniform commercially available copper fabric. A patch tag antenna is designed for each electro-textile to operate at 866 MHz. The on-body readability and Received Signal Strength (RSS) in office environment for the antennas are recorded and analyzed.
