This paper presents an optimization of a Two-Section Dual-Band Branch-Line Coupler (BLC) with stepped-impedance-stub lines (SISL), that exploit the nonuniform impedances of the coupler branches. The optimization has been done using an adjusted optimization surrogate-based method. This enhanced BLC operates over n50 and n48 bands, that belongs to 5G NR frequency bands developed by 3GPP for the 5G (fifth generation) mobile network. The simulated results validate good dual-band performances at the
