“…To increase near‐metal performance in the near‐field, a spacer between the antenna and the nonRF‐friendly material can be used. Research by Arora et al in the far‐field has shown that the use of a spacer can bring the reading performance from 77.6% (no spacer) up to 91.6% (5 mm polymethyl methacrylate (pMmA) spacer), or even up to 94.7% (10 mm PMMA spacer).…”

This article investigates the effects of the environment on ultrahigh frequency (UHF) radio frequency identification (RFID) tags in both the near‐field and far‐field. Item‐level tagging has always been challenging due to the negative impact of metals on RFID. Full‐scale RFID item‐level tagging has always been difficult to integrate in retail (department) stores. This UHF RFID feasibility research examines the technical differences between near‐field and far‐field coupling by testing theoretical hypotheses through empirical experiments. These experiments are based on a specific case‐study, where a distributor wants to tag multimedia objects. Based on the results obtained, we found that metal had less effect on the RFID tags in the near‐field than in the far‐field. In both cases the RFID tag was not readable, when placed directly onto metal. When the multimedia object itself was tagged, the reading range decreased to around half the free‐space reading range in near‐field and far‐field. We can conclude that the RFID implementation in the retail store is feasible, but depends to a large extent on the product and its environment. © 2014 Wiley Periodicals, Inc.

Metallic equipment and objects require special attention for identification in a Radio Frequency Identification (RFID) system, due to their interference negative effects. This paper presents an application of ultra-high frequency RFID in a gateway configuration, used to identify metallic equipment. The main purpose of the proposed system is to identify items with metallic content and regardless of their position when passing through the gateway. The UHF (Ultra High Frequency) RFID technology with passive tagging was implemented. Different tagging configurations were tested and results for each configuration are presented.

“…Various studies [15][16][17][18][19][20] have emphasized the fact that, the performance of RFID system in the close proximity of metals and liquids was severely affected. The extent to which the performance was degraded depends on several combinations of factors such as conductivity of the metals [12], permittivity and permeability of the metals, thickness of the metals as well as proximity of the RFID system to the metals.…”

“…The reflected waves will augment or decrease the magnetic field distribution around the metal depending on whether they in phase or out of phase with each other. Similarly presence of water drives the RFID to degrade its performance because water has a higher dielectric constant [17]. Now a day, most of the manufacturing industries prefer RFID for automatic identification of products.…”

“…This requires a thorough study to analyse the performance of RFID when it is in close proximity to various metals and water. Although sufficient literature [16][17][18][19][20] are available with regard to ultra high frequency RFID performance in metal environment and water , it is essential to test every RFID system under these conditions before they are going to be implemented in real time scenarios. Keeping all these facts in mind, the proposed work is comprehensively evaluating the performance of passive ultra high frequency RFID when they are in close proximity to several types of metals and water.…”

The objective of the proposed work is to observe the changes in the performance of passive ultra high frequency (UHF) radio frequency identification system (RFID) when it was placed closer to several types of metals present in industries and water. The change in performance of the RFID reader was calculated in terms of change in number of tag reads per second and the change in read distance between tag and reader. In order to observe these effects in real time environment, we have considered five numbers of metals with different material characteristics and potable water with less salt content were undertaken for this study. We conducted the experiments in room which is partially shielded from interferences of any type.The tags were fixed in different materials at its centre and kept at different distances from RFID reader antenna. At each distance, the performance of the RFID reader was measured. We also conducted the tests to verify the whether the tag was read when it was fixed on water container. From the results obtained, we found that the performance of the UHF RFID system was not affected when they were closer to the certain types of metals we tested and water.
