A decagonal-shaped split ring resonator metamaterial based on a wearable or textile-based material is presented in this work. Analysis and comparison of various structure sizes are compared considering a compact 6×6 mm 2 metamaterial unit cell, in particular, where robust transmissionreflection (RTR) and Nicolson-Ross-Weir (NRW) methods have been performed to extract the effective metamaterial parameters. An investigation based on the RTR method indicated an average bandwidth of 1.39 GHz with a near-zero refractive index (NZRI) and a 2.35 GHz bandwidth when considering epsilon negative (ENG) characteristics. On the other hand, for the NRW method, approximately 0.95 GHz of NZRI bandwidth and 2.46 GHz of ENG bandwidth have been observed, respectively. These results are also within the ultrawideband (UWB) frequency range, suggesting that the proposed unit cell structure is suitable for textile UWB antennas, biomedical sensors, related wearable systems, and other wireless body area network communication systems. Keywords-metamaterial, near-zero refractive index (NZRI), negative-index metamaterial, epsilon negative (ENG).

This paper presents a miniaturized UHF RFID tag antenna with increased gain using meander line techniques and metamaterial (MTM). The designed tag operates in the UHF RFID frequency band ranging from 860 to 960 MHz. It comprises of meandered lines with two hexagonal split ring resonators (H-SRRs) MTM cells. It is designed on a photo paper as its substrate which is 0.27 mm thick, with a dielectric constant of 3.2 and loss tangent of 0.05. Next, an RFID tag (NXP SL3S1213 UCODE G2iL chip) with an impedance of 23-j224 Ω is integrated with the proposed antenna to assess its performance in terms of reflection coefficient, antenna gain and maximum reading range. The overall size of the tag is 92 mm x 26 mm.

In this paper, a compact UHF RFID tag antenna that can operate at Malaysia UHF RFID frequency (860 MHz – 960MHz) is proposed. The antenna with a common geometry structure without any shorting pin consists of 90degree angled line (meander line) and double T-match structure. The proposed antenna has been designed and simulated using CST Simulation software. The proposed tag antenna design shows a good performance in terms of size, gain and impedance with a dimension of 36 mm × 25 mm × 1.6 mm. The simulated gain of antenna obtained is -0.135 dB at 910 MHz with 19 MHz bandwidth.

This paper describes a smart monitoring gate-less system by using RFID technologies that had been implemented in Universiti Malaysia Perlis. The objective of this system is to ease the security to monitoring the cars-in and cars-out from the main gate manually. The security can check and manage the staff by system management in PC. This smart monitoring gate-less system consists of RFID tag antenna that be attached at sticker’s staff, RFID reader and software management application. For the software management application, this project used LabView as a simulation tool for the data acquisition. The data which contains of name, staff number, number plate, car model and color will be stored in cloud-based storage. All the information data can be accessed from any location because the security management can access it through mobile. This project will present how efficient the vehicle control application on campus which enable the security guard to check a car sticker either legal or illegal in a shortest way.

Throughout this modernization world, the demands on Internet of Thing keep increasing. Most mailbox or pigeon hole are designed with poor efficiency system and commonly suffer from some possible flaws such as manually checking the letter by the user. The main problem of this project is to improve the existing pigeonhole system. In the case of staff at School of Computer and Communication System, Universiti Malaysia Perlis, each academic staff has been allocated a pigeon hole for any letters or memos from within or inter faculty. Unfortunately, the current conventional pigeon hole system is unable to inform and notify the staff on any urgent letter and this lead to significant delay in responding the letter. The main weakness of the current system is that staffs need to check their respective pigeon hole every day. However, due to the routine commitment or unforeseen circumstances the pigeon hole cannot be possibly checked every day. Hence, to fulfil this requirement, this project named as Smart Electronic Pigeon Hole System is introduced in order to make the pigeon hole more efficient. The purpose of this project is to design a smart electronic pigeon hole system with some detecting sensors such as infrared and ultrasonic sensors. Wi-Fi module acts as a tool to communicate via email between pigeonhole’s system and its owner. Arduino board is used to be programmed in such a way to process the sensors when detecting the upcoming document or letters and to continuously check the status of capacity of the pigeon hole. This project work with the administrative staff, who collected the documents from the post center, will entered and select the designated number of the pigeon hole users. Infrared sensors, located at the front, will detect the upcoming documents or letters. Ultrasonic sensor will detect the fullness of the letter in the pigeon hole. When there is arriving of document or letters, the user will get the notification email. The user will also get the warning notification email when their pigeon hole is full with documents. Red LED will light on when the capacity of the pigeon hole is full. The sensor will continually sense the condition of the pigeon hole as long as the system is activated. This project is suitable for the staff or the apartment residents as it has the capability to alert the user when there is a letter to prevent the urgent letter’s being ignored.
