本文提出了一种新的解析型多波段横向耦合矩阵合成技术。将多个单带滤波功能合理组合，可以得到传输零点灵活、带宽多样的多带滤波功能。然后将横向耦合方案转化为可实际实现的耦合方案。为了验证所提方法的可行性，提出了两种双带耦合方案，即单路和双路，作为双带滤波器设计的实例。最后，基于特定耦合方案对应的耦合矩阵，采用微带并联耦合结构实现双带滤波器。
In this paper, we present a novel analytical multiband transversal coupling matrix synthesis technique. By properly combining several single-band filtering functions, the multiband filtering function with flexible transmission zeros and various bandwidth are available. The transversal coupling scheme is then transformed into a practically realizable coupling scheme. To verify the feasibility of the proposed method, two dual-band coupling schemes, both single-path and dual-path, are proposed as examples of the dual-band filter design. Finally, the dual-band filter, based on the coupling matrix corresponding to a specific coupling scheme, can be realized using a microstrip parallel-coupled structure.
