“…The structure of the CSRR is shown in Figure 2. We have adopted the analytical equation for CSRR resonant frequency accomplished which is addressed in [16][17][18][19][20][21][22][23][24]. By using the (1-3), the average ring length (A), outer length (a1), and inner length (a2) of CSRR structure are correspondingly measured as follows: The dimension of the ring split (s) and width (w) was set to 0.2 mm.…”

<span>This paper presents a compact microstrip ultra-high frequency (UHF) reader patch antenna with complementary split ring resonator (CSRR) for radio frequency identification (RFID). The total size of the antenna is 208 × 208 × 1.6 mm<sup>3</sup>. The proposed antenna is designed, fabricated and measured in order to verify the proposed concept. The characterization for radiation parameters, like return loss, radiation pattern and antenna gain have been done experimentally. The proposed antenna is operated at 921 MHz for and achieved a gain of 8.285 dBi. All simulations in this work have been carried out by means of the commercial computer simulation technology (CST) software. In compare to the simulated results, the measured outcomes are promised.</span>

“…In addition, RFID can be implemented in harsh environments such as dirt and damage, providing the ability of auto-tracking [8]. RFID can identify tags without the need for direct contact where it can identify tags for a specific object within couple feet, tag reusability, and the ability to read multiple tags simultaneously [9,10]. These functions make RFID technology more preferable over other technologies like barcoding in the field of smart environments like a smart library, smart University, security systemconsidering cost, etc.…”

Electronic payment has been considered as one of the most significant and convenient applications of modern electronic services e-University compared to traditional methods that impose time-consuming, human resources, and inefficiency. Different automatic identification technologies have been widely used, such as radio frequency identification (RFID). Extensive research and several applications are focusing on taking the maximum advantage of RFID technology. Data and information security had considered a crucial role when information concerning e-commerce, e-banking, or e-payments, especially due to it required real data to establish accessed illegally. Hence, data originality and security fall a very significant and critical issue in data communication services in recent years. Applications such as e-banking or e-commerce regularly contain sensitive and personal information that should be managed and controlled by authorized persons. Thus, keeping a secure password is important to prevent unauthorized users from illegal access. The password hashing is one of the safety methods and means of preventing attacks. In this article, focuses on proposing an RFID based electronic payment and also provide multi-level security privileges for an academic domain by using RFID technology besides the programmable logic circuit as well the system used C# language in visual studio environment also desktop and web-based application for system working purposes. The proposed system aims to manage student payments in a secure manner and provides the capabilities of getting a bus ticket, copying books, buying food, paying registration fees, and other services. The results have shown the system is secured by using the confirmation code in addition to password encryption.

“…Four principal frequency ranges exist: Low Frequency (LF: 125 KHz), High Frequency (HF: 13.56 MHz), Ultra-High Frequency (860-960 MHz), and Microwave band (2.45/5.8 GHz) [2], [3]. In particular, UHF passive RFID systems are very advantageously compared to regulate passive RFID systems [4] using low frequency and high frequency bands, as they can provide a greater and faster reading range and better information storage capacity [3]. Worldwide, the UHF band for RFID systems ranges from 860 to 960 MHz where each country/region has a unique frequency band.…”

This article suggests a simple and new miniaturized antenna for radio-frequency identification (RFID) tags in the European and Moroccan UHF band (866-869 MHz). Our structure consists of a meandering dipole, L-shaped radiators and a changed T-Match network. The meander technique was applied to decrease the antenna size; using this method, the size of our structure has been reduced to 68% compared to the classical UHF dipole. L-shaped radiators and a modified T-matching approach are also used to easily match the antenna input impedance to that of the chip to maximize power transfer. The size of our antenna is 50 x 22 mm 2 , it has been designed on a single-sided FR-4 substrate with a thickness of 0.8 mm for a relative permittivity, Ɛr of 4.4. For our design, we chose the Higgs 4 IC chip (manufactured by Alien Technology, USA) which has an impedance of 20.5-j191 Ω obtained at the centre frequency 867 MHz. The antenna performance was studied with respect to the impedance matching, realized gain, reflection coefficients and read range of the label. Therefore, the proposed design achieved a gain of 1.2 dB and a maximum reading range of 13.94 meters at 867 MHz.
