Ultra-high frequency RFID (UHF-RFID), defined by the EPC Gen2 standard, uses the unlicensed band in the 915 MHz range in the United States. RFID sensor tags consist of an antenna, a radio .Abstract: In this paper a multi-system, multi-band antenna structure for RFID applications is presented. The antenna covers two UHF bands allocated for RFID use in Europe (866-868 MHz) and N. America (902-928 MHz) with a dual-band PIFA element as well as HF 13.56 MHz band with a near-field coil.UHF multi-antenna RFID readers provide powerful solutions for applications requiring broad, simultaneous coverage of multiple zones. Equipped with multiple antennas, these readers can monitor large areas, making them ideal for high-volume asset tracking and complex environments.In this paper, a broadband UHF RFID tag is proposed. By introducing a coupling loop and four bent dipoles, two resonant modes are excited in UHF RFID band, which results in a total 194 MHz (806MHZ-1GHz) 3dB operational bandwidth. It covers the entire UHF band (860 MHz-960MHz).

Frequency-ranges used for RFID-systems. As shown in Fig. 4, several frequency bands have been assigned to RFID applications: 125/134 KHz, 13.56 MHz, 860-960 MHz, 2.450 (2.400–2.483) GHz and 5.800 (5.725–5.875) GHz. Several issues are involved in choosing a frequency of operation (Dobkin 2007).
This study proposes a new, low-cost tri-band rectenna operating in UHF RFID, GSM-1800 and UMTS-2100 frequency bands. The waves operating in these three frequencies bands come from RFID applications and access networks of telephone operators deployed in the human environment. In this paper, we presented RFID multi-band reader antenna design that is worked in four UHF standard bands to cover all around the world RFID classification frequencies. In this paper, we presented RFID multi-band reader antenna design that is worked in four UHF standard bands to cover all around the world RFID classification frequencies. This design works practically as a circular polarization so it will decrease the tag polarization disadvantage to the minimum eff.Dual-frequency RFID tags combine the benefits of two different frequency ranges. For example, a tag could use HF for access control purposes and UHF for inventory management purposes. This allows for more efficient and accurate tracking and management of assets and inventory.
