Design of Dual-Oriented Rectangular Dielectric Resonator Antennas DRAs for Enhanced Bandwidth and Efficiency at Frequency 13 GHz

Abstract

The article discusses the design of dual-oriented rectangular dielectric resonator antennas (DRAs) to enhance gain and efficiency at 13 GHz. The study focuses on improving antenna performance by configuring two rectangular DRAs oriented both vertically and horizontally within a single structure. This dual orientation leverages the advantages of each configuration to achieve higher gain and improved efficiency, specifically at the frequency of 13 GHz. The research addresses the technical challenge of optimizing antenna parameters to enhance performance, targeting a gain increase to 7.033 dBi and an efficiency improvement to 94.4%. These advancements are crucial for applications requiring reliable, high-performance signal transmission at this frequency. Additionally, the study focuses on reducing the size of the ground plane and substrate while modifying the geometry of the feed to enhance the radiation pattern compared to previous designs. The design improvements are evaluated using the Computer Simulation Technology (CST) program.
