Implementation and application of UHF RFID antenna
RFID tags come in many forms but all comprise an integrated circuit on which in use data can be stored and a coil which enables it to be interrogated by a reader which also powers it by means of a wireless link. The most common different transmission frequencies are classified into the four basic ranges, LF (low frequency, e.g. 125KHz), HF (high frequency, e.g. 13.56MHz), UHF (ultra high frequency, e.g. 868MHz or 915MHz) and microwave (e.g. 2.4GHz ). In this paper, design and fabrication of the UHF RFID antenna is presented.
