Characteristics and Application of a Novel Loop Antenna to UHF RFID Receivers
RadioFrequency IDentification (RFID), which was developed around World War II, is a technology that provides wireless identification and tracking capability. The reader antenna is an important unit of the RadioFrequency IDentification (RFID) systems. Many new developed RFID antennas are reported recently. There are two different types of reader antennas including the near-field antenna and the far-field antenna. Currently, UltraHigh Frequency (UHF) near-field RFID technology receives a lot of attention due to the promising opportunities in item-level RFID applications such as sensitive products tracking, pharmaceutical logistics, transport and medical products (blood, medicines, and vaccines), and biosensing applications.
