چکیده

Radio Frequency Identification (RFID) systems operating in the Ultra High Frequency (UHF) band, are exposed to fading. While state-of-the-art RFID systems employ multiple antennas, with random selection of a single receive path to obviate the performance losses, this paper proposes to employ antenna diversity by the combination of all paths applying maximal ratio combining. An experimental performance comparison of maximum ratio combining and random antenna selection with two receive antennas in a high fading environment is given, which demonstrates the superior performance of our proposal.

RFID Antenna Performance Evaluation for Library Inventory Management

Three types of printed radio-frequency-identification (RFID) antennas with the characteristics of high gain, wide beam wave, and omnidirectional beam wave are constructed and evaluated in this study. The objective is to find out their best reading rates for providing effective wireless communications among RFID antenna readers during the library book inventory process. Three kinds of antenna re...

Compact 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...

Dual Band Slotted Patch Antenna for On/Off-body Communication

Body Centric Wireless Communication (BCWC) has been topic of much research in recent years. In this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communication with a dual-band operation. The proposed structure exhibits a monopole-like radiation pattern at 2.45 GHz and a broadside radiation at 4.8 GHz, simultaneously. Lateral dimensions of 42 mm × 46 mm and ...

A compact stacked Quasi-fractal microstrip antenna for RFID applications

In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...

A Broad-Typed Multi-Sensing-Range Method for Indoor Position Estimation of Passive RFID Tags

The RFID (Radio Frequency IDentification) system is paid attention as a technology that can realize a ubiquitous environment. Each RFID tag has a unique ID code, and is attached on some object with the information of the objects. A user reads the unique ID code using RFID readers and obtains the information of the object. One of the important applications of RFID technology is the indoor positi...
