An ultra-wideband comb-slot-fed symmetrical comb-groove-dielectric resonator antenna (CGDRA) for B5G/6G millimeter-wave (mm-wave) applications is presented in this letter. The proposed CGDRA consists of the comb-slot feeding and the two symmetrical comb-groove-DR (CGDR) elements, which can generate multiple resonance modes for the wideband operation. The sound-fork-shaped microstrip line is adopted to feed the CGDRA through the comb-slot. The bowl-shaped metal wall is arranged around the CGDR to
