Abstract
The utility model provides a metamaterial-based vehicle-mounted RFID antenna system, comprising an RFID antenna, an RFID module, a microprocessing unit, and a vehicle-mounted central control center, which are sequentially connected. According to the utility model, the built-in metamaterial RFID antenna is employed to replace a traditional PCB antenna and a Meta-RF wireless technology is applied so that on the basis of guaranteeing the RFID transmission and reception performance, an integral whole machine design is formed through internally arranging the antenna and the installation time and cost are reduced. In terms of the reception performance, the antenna system is good in omnidirectivity and beneficial for good reception under various environments. Therefore, with the utilization of a metamaterial technology's ultra-sensitive signal reception capability and the cooperation of an active RFID scheme, the effective detection and communication by an RFID reader can be guaranteed during high-speed driving or within long-distance ranges.
Description
Technical field
The utility model relates to a kind of vehicle-mounted RFID antenna system, relates in particular to a kind of vehicle-mounted RFID antenna system based on super material.
