This tag uses a novel mechanical BPSK backscatter modulator driven by a high speed rotating shaft to telemeter a 32 bit unique ID as a BPSK symbol sequence at a rate synchronous to the rotation of the shaft. The tag integrates a 9 dBi linearly polarized air-dielectric patch antenna. It is a proof of concept for applications in remotely identifying components and measuring rotation rates in high speed, high temperature equipment such as jet engines, industrial turbines, and down-hole oil drilling equipment. To ensure high reliability, there are no switch contacts in this design. Unlike traditional CMOS IC based RFID tags, this tag has no RF power-up threshold and can be interrogated at an extremely low incident power. Unlike SAW and multiple resonator based chipless tags, an unmodulated 2.4 GHz CW excitation is sufficient to read out the digital bit stream from the tag. In laboratory testing, a read range of over 2 m is achieved with an interrogator power of only +5 dBm. At a rotation rate of 206.8 RPM, the tag telemeters data at 110.3 symbols per second. The approach can easily be extended beyond 32 bit IDs.","PeriodicalId":251364,"journal":{"name":"2017 IEEE International Conference on RFID (RFID)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115364552","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}

Several methods for employing perfect pulses in digital modulation schemes, with particular emphasis on backscatter (and simply scatter) radio modulation, are demonstrated. These waveforms enable a completely new type of RF information exchange by piggy-backing useful information onto ambient wireless signals using low-powered electronics. A mathematical model of perfect pulses is shared as well as an overview of their spectral properties. Software simulations of perfect pulse enabled communications depict the creation of the channel waveforms, modulation onto a pseudo-random ambient carrier, and retrieval of the intended message data from the noisy and interference laden received signal. A robust receiver system is described which can be implemented via simple post-processing techniques in a software defined system or as a low-cost, low-power RF circuit using commercial-off-the-shelf components. Experimentally retrieved data is used to create a realistic estimate of bit rate errors using an actual FM radio station signal.","PeriodicalId":251364,"journal":{"name":"2017 IEEE International Conference on RFID (RFID)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116683838","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 HPMU strategically takes advantage of the excess harvested power beyond the operational requirements of a tag and stores this energy externally. Through intelligent power routing, this stored energy is used to sustain the supply voltage of tag circuitry during brownouts, cold starts, and for reading ranges where harvested power is inadequate to power tag logic circuits but the tag distance to an interrogating antenna is close enough to expect a backscattered response to be received by an RFID reader. This approach can reduce cold start-up time, mitigate consequences of brownouts and, effectively, extend the operational range and the responsiveness of tags—especially those with passively powered sensors. In addition, the HPMU switches off when the harvested power, indicative of a weak interrogating signal, is too low to conserve stored power. The entire HPMU has been optimized for low power consumption, which not only reduces the power overhead that HPMU introduces but also ensures that as much power as possible is siphoned and stored rather than dissipated in the power management circuitry. In off state, the HPMU consumes only around 10 nA from the external storage element and during charge storage mode of operation, the HPMU has a peak conversion efficiency of approximately 65%.","PeriodicalId":251364,"journal":{"name":"2017 IEEE International Conference on RFID (RFID)","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123030748","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}

Use of directional antennas in RTI nodes focuses RF power along the link line, improving system performance. However, antennas placed on a building's exterior wall can be detuned by their close proximity to the dielectric, thus sending power across wider angles and resulting in less accurate imaging. In this paper, we improve through-wall RTI by using an E-shaped patch antenna we design to be mounted to an exterior wall. Along with its directionality, the E-shaped patch antenna is designed to avoid impedance mismatches when brought into close proximity of a dielectric material, thus increasing radiation through the exterior wall and along the link line. From our experiments, we demonstrate that the E-shaped patch antenna can reduce the median root mean square localization error by up to 43% when compared to microstrip patch and omnidirectional antennas. For equal error performance, the E-shaped patch antenna allows an RTI system to reduce power and bandwidth usage by using fewer nodes and measuring on fewer channels.","PeriodicalId":251364,"journal":{"name":"2017 IEEE International Conference on RFID (RFID)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121640024","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}
