The present disclosure relates to communications technologies, and provides a single polarized ME dipole and a basic radiator of a phased array antenna for millimeter wave or above frequency band. The radiator is an “array of the ME dipoles” with higher dielectric constant, and can be manufactured with the multilayer PCB or LTCC process. The ME dipole comprises an electric dipole made by two parts of a first metal sheet located on a top substrate layer, a magnetic dipole made by first vias connected to the first metal sheet and a third metal sheet located on a bottom substrate layer, a balun made by an other part of the first metal sheet and a third via, and a reflecting part made by a part of the third metal sheet. The substrate layers are stacked in a multilayer structure to facilitate arranging the metal sheets and the vias.
