RFID-Tag Antenna Design

The Radio frequency identification (RFID) technology essentially consists of the reader, tag and host computer.Since the passive RFID tag does not have its own power source, therefore, the continuous sending signal by the RFID reader¿s antenna through the air acting as activate the tag to send the information to the reader.This Research Presents small low cost passive UHF -RFID tag prototype has been designed and applied for metallic object it can also be used in tracing and tracking object it can be used in logistics and supply chain.The tag can modified into non-metallic application such that tag can be attached to the clothes of humans for tacking and it also can be used in identification of animals, While the tag antenna presented in this project are designed to be as simple as possible with low cost.
