Abstract
This letter proposes a differentially-fed broadband dipole and its 1×8 array. The antenna achieves cost-effectiveness by using a low-cost FR4 substrate. The antenna obtains surface mount capability due to the ball grid array (BGA) package. The measured results show that the proposed antenna array achieves a wide impedance bandwidth of 37.8% (24-35.2 GHz). The gain of the 1×8 array is greater than 10.1 dBi, and the cross-polarization level in the main beam direction is less than -20 dB. the radiation pattern of the 1×8 array is stable and unidirectional. The proposed antenna array covers the 5G N257 (26.5-29.5 GHz), N258 (24.25-27.5 GHz), and N261 (27.5-28.35 GHz) bands.
