ABSTRACT
This research focuses on developing a Compact, dielectric resonator antenna that is rectangular (RDRA) optimized for vehicular communication at 3.6 GHz. Using a microstrip feed technique and FR4 substrate material with a dimension of 50×50 mm and 1.6 mm in thickness and 4.4 die-lectric constant. It exhibits a return loss of -24.378 dB, indicating excellent efficiency and im-pedance matching, with a VSWR of 1.050 showcasing minimal signal reflection. With a gain of 6.8 dBi, crucial for reliable signal propagation in dynamic vehicular environments. The design makes use of HFSS software. The antenna offers robust performance. Methodologically, exten-sive simulations and prototyping refine the antenna's parameters, emphasizing precise impedance matching to minimize signal loss. The use of FR4 substrate material ensures cost-effectiveness and practicality in fabrication, contributing to scalability for real-world applications. This re-search contributes on developing a Compact, dielectric resonator antenna that is rectangular (RDRA) for vehicular communication, offering a promising solution for improving connectivity and reliability in future vehicular communication (VCS).
