Sensor Network in the Wireless UHF Band
Biological research in agriculture needs a lot of specialized electronic sensors in order to fulfill different goals, like as: climate monitoring, soil and fruit assessment, control of insects and diseases, chemical pollutants, identification and control of weeds, crop tracking, and so on. That research must be supported by consistent biological models able to simulate diverse environmental con...
متن کاملVibration Powered Battery-Assisted Passive RFID Tag
Real-time supply chain management, theft prevention, and environmental monitoring motivate the need for RFID systems. Battery-assisted RFID tags increase read range and reliability; however, batteries offer only a finite lifetime solution. Hence, an experiment in powering a battery-assisted passive RFID tag using ambient vibration energy was conducted. A piezoelectric power generator was design...

15 صفحه اولPerformance Comparison of RFID Tag at UHF Band and Millimeter-Wave Band
The ultra high frequency (UHF) band spectrum will likely be congested in near future since the next generation wireless as well as Radio Frequency Identification (RFID) system users will witness the use of UHF band technology with increased demand of bandwidth, bit rate, frequency spectrum and power consumption. The alternate solution is the use of millimeter-wave band technology. It is possibl...
متن کاملMultiport Circular Polarized RFID-Tag Antenna for UHF Sensor Applications
A circular polarized patch antenna for UHF RFID tag-based sensor applications is presented, with the circular polarization (CP) generated by a new antenna shape, an asymmetric stars shaped slotted microstrip patch antenna (CP-ASSSMP). Four stars etched on the patch allow the antenna's size to be reduced by close to 20%. The proposed antenna is matched with two RFID chips via inductive-loop matc...
