A Novel Tag Identification Algorithm for RFID System Using UHF
An anti-collision algorithm is very important in the RFID system, because it decides tag identification time and tag identification accuracy. We propose improved anti-collision algorithms for RFID system using UHF. In the proposed algorithms, if the reader memorizes the Bin slot information, it can reduce the repetition of the unnecessary PingID command and the time to identify tags. If we also...
متن کاملUHF RFID Reader Antenna using Novel Planar Metamaterial Structure for RFID System
An Ultra High Frequency (UHF) half-loop antenna used in Radio Frequency Identification (RFID) systems is proposed with a planar patterned metamaterial structure of compact size. The size of the planar patterned metamaterial structure is (0.20λ*0.20λ*0.0023λ) mm. This antenna consists of two metamaterial unit cells having negative permittivity and permeability. Simulation results of input return...
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 کاملDCSK Multi-Access Scheme for UHF RFID System
DCSK modulation in chaos communication is a robust non-coherent modulation scheme. In this paper, the multiple-access DCSK scheme based on the OVSF code is proposed. Using the multiple-access DCSK scheme in RFID system, a DCSK-RFID system is presented. In the presented DCSK-RFID system, we use the DCSK for tag modulation for its low complexity and the simple receiver of the DCSK scheme is appli...
متن کاملNanotube in a periodic potential: A conveyer belt for electrons
We consider a carbon nanotube gated slightly away from the half-filled π-band, in the presence of an externally applied periodic potential. We show that the electron states can become locked by the potential when the electron density (counted from half-filling) corresponds to a rational number of electrons per potential period. At such densities, excitation gaps open up in the spectrum. When ga...
