RFID-Based E-Plate with Slot-Dipole Antenna Design and Roadside Inter- rogator Deployment
نویسندگان
چکیده
For some scenarios of vehicle tracking and identification, it is desired that radio-frequency identification (RFID) interrogators can be deployed on roadside lampposts or high poles. In order to meet this requirement, active RFID electronic license plate (e-plate) with a slot-dipole antenna is proposed to provide up-tilted beams. Numerical simulations demonstrate that the proposed e-plate antenna has desired impedance bandwidth, high gain and multi-beam radiation pattern as required at 2.45 GHz RFID band. In addition, the estimated read range of the proposed e-plate meets the requirement of RFID system, and deployment of interrogator on roadside lamppost or high pole is analyzed.
