Abstract— An overview of the state-of-the-art of the antennas for ultra high frequency (UHF) near-field (NF) radio frequency identification (RFID) readers is presented. The specific requirements, design considerations, and design guidelines are addressed. A segmented loop antenna with capacitive couplers is proposed for ultra-high frequency (UHF) near-field radio frequency identification (RFID) applications, which is capable of generating a strong and uniform magnetic field in a near-field zone even though the perimeter of the loop is comparable to the operating wavelength. This paper presents our investigation into a novel ultrahigh-frequency (UHF) radio frequency identification (RFID) multipolarized reader antenna based on a pair of symmetrical meandering open-ended microstrip lines for near-field applications.
