A fractal dipole antenna for passive UHF RFID applications has been proposed. The NF-focused array... The book introduces a design of different antennas for RFID tag and readers. an elliptical dielectric resonator antenna fed by single feed with rectangular ground is proposed for radio frequency identification (RFID) reader operating at center frequency of 5.8 GHz.The effects of the presence of portable reader device and human hand on the radiation characteristics of the antenna are investigated.An 8?8 NF-focused EDRA phased array for fixed RFID reader applications is investigated. The radiation characteristics and backscattering from the tag antenna in free space, mounted on cylindrical bottle and mounted on spherical bottle have been considered. The antenna is simple and has good impedance matching with the chip impedance. The book proposes and studies the parameters of an OFHA for handheld UHF RFID reader. A curved dual-band ring dielectric resonator tag antenna has been presented!
