ABSTRACT
This research paper presents a comprehensive design, simulation, and analysis of a rectangular Dielectric Resonator Antenna (DRA) optimized for operation at 3.6 GHz. Utilizing the High-Frequency Structure Simulator (HFSS) software, the antenna design integrates a microstrip line feed combined with a hexagonal shape to enhance impedance matching and power transfer efficiency. The substrate material employed is RT Duroid 5880, recognized for its superior dielectric properties, including a low loss tangent and high dielectric constant. The antenna's dimensions are set at 50 mm x 50 mm x 1 mm to achieve compactness without compromising performance. Simulated results demonstrate outstanding performance metrics, including a return loss of -33.4934 dB, a Voltage Standing Wave Ratio (VSWR) of 0.409, and a gain of 8.6 dBi, underscoring the antenna's excellent impedance matching and high radiation efficiency. The proposed DRA design offers a compact, cost-effective, and high-performance solution suitable for various wireless communication applications, highlighting its potential for future integration in advanced communication systems.
