RFID or Radio Frequency Identification refers to the technology of transmitting the identity of people or objects wirelessly as a unique code [1]. This technology is divided into four categories depending on the frequency band in which it is operated: low frequency (LF), high frequency (HF), ultra-high frequency (UHF) and microwave frequency (MW). UHF RFID flourished when the Auto-ID centre at Massachusetts Institute of Technology was established in 1999 [2]. This type of RFID has several advantages compared to other types including higher data rates, requiring only simple dipole-like antennas, and longer ranges [3]. Standards of use of RFID's depend on the country in which they are used. In Australia, the allocated band for UHF RFID is 918 MHz- 926 MHz [3]. This paper proposes an array of three compact phase shifters for use in UHF RFID applications such as phased array antennas. The proposed phase shifters operate at 910 MHz with a bandwidth of 100 MHz, thus covering the Australian band completely.
