Design and Optimization of Dual-Band Branch-Line Coupler with Stepped-Impedance-Stub for 5G Applications

by Ayyoub El Berbri, Adil Saadi and Seddik Bri

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 3, Page # 355–360, 2020; DOI: 10.25046/aj050346

Abstract:

This paper presents a design optimization of a dual-band branch-line coupler with stepped-impedance-stub lines. This coupler operates over 5G NR frequency bands n5 and n2, developed by 3GPP for the 5G (fifth generation) mobile network, and these two bands are centered at 0.85 GHz and 1.9 GHz respectively. To achieve the design specifications an adjusted…
