This paper presents a differentially fed, dual-band dual-polarized antenna, suitable for 5G millimeter-wave, base station antenna array. The operating frequency range covers all the millimeter wave frequencies allotted in 5G NR from 24.25 GHz up to 40 GHz. Stacking technique is utilized to achieve wide dual bands and stable radiation pattern. The antenna geometry is simple, adhering to commercial multi-layer PCB fabrication requirements. Antenna design procedure and simulated results are discussed. The operating frequency of the lower band starts from 24.25 GHz up to 29.5 GHz while the higher band covers the 37 GHz to 40 GHz. The realized gain remains stable between 5 to 6 dB at all the operating frequencies. The isolation between the ports and cross-polar discrimination remain better than 30 dB in all the operating frequency range.
