A dual-frequency band high-gain split-ring antenna is proposed for 5G mm-wave applications. The antenna consists of three split ring resonators (SRRs), one is the main SRR which radiates at the first resonant frequency (f 1 =24.5 GHz). The other two resonators are parasitic SRRs which act as directors to get end-fire radiation characteristics for the proposed antenna at f 1 . In addition, the two parasitic SRRs are fed by capacitive coupling with the main SRR to radiate at the second resonant frequency (f 2 =28.5 GHz). The antenna has better radiation characteristics. It has high gain values of 7.9, and 7.5 dBi with radiation efficiencies of 92% and 95% at f 1 , and f 2 , respectively. The proposed antenna is a good candidate for MIMO array at 5G frequency bands utilizing the antenna high gain to improve the system performance.
