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, res...

A post-wall waveguide-fed parallel-plate slot array antenna [1–3] has been proposed as a highgain, high-efficiency and mass producible planar antenna in millimeter-wave applications. The authors are developing post-wall waveguide slot arrays using a copper-clad dielectric substrate which reduces the cost of waveguides structures by printed circuit board (PCB) fabrication technique. The transmis...
