In this paper, we present a novel structure of a compact wideband branch-line coupler. The reduced component size is obtained by using cascaded slow-wave structures as substitutes for the main lines of the coupler, and meander lines to shorten the high-impedance branches. We exploit a surrogate-based optimization concept to design the coupler at a low computational cost. This involves electromagnetic...
In this paper, we present a methodology for expedited hierarchical simulation-driven design of miniaturized multi-section branch-line couplers (BLCs). The design process starts from optimization of elementary cells of a slow-wave structure, followed by a fast tuning of their cascade as well as the tuning of the entire coupler. The last two stages exploit surrogate-assisted optimization with the underlying...
