<span lang="EN-MY">In this paper, a wideband millimeter-wave (mm-Wave) printed dipole antenna is proposed to be used for fifth generation (5G) communications. The single element antenna exhibits a 36 GHz bandwidth with more than 85.71% fractional bandwidth (for <em>S</em><sub>11</sub> </span><!--[if supportFields]><span lang=EN-MY style='font-size:9.0pt;
