A Review of Dielectric Resonator Antenna at Mm-Wave Band

This paper is a comprehensive review of the recent literature studies on developments and applications millimeter-wave (mm-wave) dielectric resonator antennas (DRAs). Different designs techniques for linear circular polarized DRAs are discussed thoroughly. In addition, array multiple-input multiple-output (MIMO) operating in K, Ka, V bands illustrated. These highly advantageous many levels, resulting improved performance DRA terms obtaining higher gain, lower losses, efficiency, profile. work reviews fundamental research trends to meet demands fifth-generation (5G) communications beyond. The reviewed scholarly sources which contain measurement-based results. concludes by highlighting limitations implications future research.
