Efficient design procedure is introduced for the design of miniaturised contiguous band manifold‐coupled multiplexer using the combination of the circuit‐full‐wave‐based optimisation in this study. Systematic methodology is based on the design of miniaturised channel filters using circuit model extraction and H ‐plane manifold network with hybrid optimisation. The multiplexer is firstly analysed in circuit level, and relevant lengths between channel filters and the lengths between each channel filters to manifold junction are determined meticulously to compensate for the channel interaction and mismatching effects of individual channels. Then, full‐wave model is constructed and simulated by using corresponding length values. This method has been applied for the design of six‐channel contiguous band waveguide multiplexer as an illustration. The obtained results show the efficiency and validity of the proposed method.
