A quasi-Yagi antenna with parasitic cells and its array are proposed for 5G mm-wave bands. For the antenna unit, through introducing the parasitic cells, the gain could be enhanced maximum of 1.3 dB without increasing the antenna length and a wide bandwidth served for the 5G N258 band. Besides, substrate integrated waveguide (SIW) with short-circuit metal vias is employed as the feed structure and reflector, which can easily tune the impedance matching. For the antenna array, by designing a SIW power divider, the antenna element can be convenient to integrate as a 1 × 4 end-fire array. The antenna unit and its array have been fabricated and measured. The measured results show that the high peak gain of the element and array is 9.06 and 14.38 dB within the operation bands (24.25–27.5 GHz), respectively. It is suitable for miniaturized end-fire devices with 5G N258 mm-wave operation systems.
