Low Cost High Frequency Tag Antenna for an Inventory Management RFID System

This paper presents the development of a low cost passive high frequency tag antenna that is utilized for an inventory management radio frequency identification (rfid) system. The main material used in the study is the Magnetic Copper Wire. There are four types of antenna that has been designed namely the multilayer circular, multilayer rectangular, single layer circular and single layer rectangular tag antenna. Each type of antenna has some dimension and parameter combinations that is varied in order to determine the most optimized design. The designs had undergone simulation using the Computer Simulations Technology (CST) StudioSuite 2018. The chosen fabricated designs were tested using RFID Reader and a Digital Oscilloscope. Analysis and comparison of actual results were done between the chosen fabricated antennas in order to determine the most optimized designs of tag antenna.
