Abstract
This paper presents a novel design of antenna using sapphire. An aperture coupled two- layer stacked rectangular dielectric resonator antenna structure design consists of sapphire and TMM13i. Due to sapphire and TMM13i physical attributes such as hardness, resistance to physical change and chemical erosion the designed antenna is best suited for long distance, underground and rugged communication in addition to C band and 5G applications. The Aperture coupled feed has been employed because of its advantage of providing better isolation between antennas and the feed network. The designed antenna provides the gain of 5.2 dB and impedance matching of 50 ohms. The software High-Frequency Structure Simulator has been employed to simulate antenna design. The prototype of the antenna has been designed and tested on Vector Network Analyzer and Anechoic Chamber. The simulated results are in close proximity of tested results.
