Compact UHF RFID Handheld Reader Antenna and Array Based on Resonant Quadrifilar Spiral Structure
In this paper, a compact circularly polarized antenna based on a resonant quadrifilar spiral structure for the application of UHF RFID handheld reader is proposed and demonstrated experimentally. To reduce antenna size and improve impedance matching, the original resonant arms are revised by bending inverted-F structures and printing them on dielectric substrates, and the four arms are fed by a...
متن کاملUHF RFID Reader Antenna
This chapter addresses the various design issues, requirements, and specifications in designing reader antennas for UHF RFID applications. In a typical UHF system, the RFID reader antennas are geography specific; that is, there are different antennas for different geography, namely North America, Europe, et cetera. The discussion on the design challenges and performance expectations lead to a n...
متن کاملInvestigation of a Compact Dual-band Handheld RFID Reader Antenna
The design of a dual band operational compact antenna is investigated in this paper for RFID handheld reader application. The dual frequency operation of the antenna is achieved by using a U-shaped slot on the patch and a L-shaped slot in the ground plane. The shorted wall connecting the patch and the ground plane plays a vital role to make it compact. The overall dimension of the patch is 20×3...
متن کاملCompact diversity antenna for UHF RFID readers
A diversity antenna combining four inverted-F antennas (IFAs) is evaluated for UHF RF identification (RFID) readers. Polarisation and pattern diversities are obtained for a sequentially rotated configuration of the IFAs. Mutual coupling between ports is minimised by etching quarter-wavelength slots into the ground plane. The resulting envelope correlation coefficient is less than 0.003 in the w...
متن کاملPlanar, Lightweight, Circularly Polarized Crossed Dipole Antenna for Handheld Uhf Rfid Reader
A planar, lightweight, crossed dipole antenna with circularly polarized (CP) radiation is introduced for application in a radiofrequency identification handheld reader at ultrahigh frequency bands. The dipoles cross through a 90 phase-delay line of a vacant-quarter printed ring that enables broadband characteristic in terms of impedance matching and 3-dB axial ratio (AR) bandwidths. Four printe...
