الملخص

This work presents a comprehensive investigation of the resonant behavior in Rectangular Dielectric Resonator Antennas (RDRAs) using the Dielectric Waveguide Model (DWM). Analytical modeling and MATLAB-based numerical simulations are combined with validation from CST and eigenmode solvers to thoroughly evaluate the influence of geometrical parameters and dielectric permittivity on mode excitation. The study also demonstrates the effectiveness of aperture-coupled feeding techniques in achieving selective mode excitation. These results provide a solid foundation for optimizing RDRA designs aimed at advanced wireless and electromagnetic applications.
