Multiport UHF RFID-Tag Antenna for Enhanced Energy Harvesting of Self-Powered Wireless Sensors PROJECT TITLE :Multiport UHF RFID-Tag Antenna for Enhanced Energy Harvesting of Self-Powered Wireless SensorsABSTRACT:This paper presents the planning and experimental analysis of an extended-range solar powered sensor-enhanced radio frequency identification (RFID) tag. The tag antenna may be a multiport microstrip patch with an overlay of skinny-film solar cells for energy harvesting. A second port is allocated on the patch antenna for supplementary energy harvesting from the RF signal transmitted by the reader. An $I^2C$-RFID chip together with a microcontroller unit (MCU) and temperature and humidity sensor are incorporated into the tag design to implement a low-value wireless sensor employing a business RFID reader. The measurements of the fabricated RFID-tag sensor demonstrate that a most sensing/reading vary of 27 m is achieved when all the circuits are powered using solar cells, whereas it's 7.48 m with solely the secondary choice of energy harvesting. The proposed sensor with dual energy harvesting achieves each a longer vary and a lifetime compared with similar battery-powered sensor-enhanced RFID tags. The RFID sensor is also evaluated in a very climate chamber and the sensor knowledge (temperature/humidity) were remotely recorded with an glorious accuracy using a business ultra high frequency (UHF) RFID reader. Moreover, the sensor can be programmed for the temperature/humidity surveillance of sensitive things, like those found in varied provide chain and transportation applications.
