Witrynathe reader, the response of the tag is returned as a backscattered RF signal during the CW period. In the passive RFID system, the power, harvested by the tag, directly determines the read/write (R/W) range or identification range between the reader and tag. The tags need to backscatter sufficient power to satisfy the reader sensitivity. WitrynaThe RFID technology objective applied to the vehicular identification is to have all the motor vehicle information, for example, owner name, license, fines, etc. It is a radio mobile typical application, the figure 1 shows the radio channel components, the reader, the tag, the direct ray and the reflected ray from the surface, where the reader ...
