本文介绍了用于双频段操作的威尔金森功率分配器的新设计。首先提出了两种类型的双频带四分之一波长 (λ/4) 传输线，其中应用了开路短截线。然后使用 ABCD 矩阵推导这些双带线的设计方程。基于这些方程，我们发现所提出的结构具有较大的频率比范围（从 2.16 到 4.9）。通过用这些双频带线替代传统的 λ/4 线，可以实现所需的双频带威尔金森功率分配器。利用该方法设计了工作在1.8/5.8GHz的功分器。其测量的性能验证了设计理念。
This paper presents new designs of Wilkinson power dividers for dual-band operations. Two types of dual-band quarter-wavelength (λ/4) transmission lines are proposed first, where both open- and short-ended stubs are applied. ABCD-matrix is then employed to derive the design equations of these dual-band lines. Based on these equations, it is found that the proposed structures feature a large frequency ratio range (from 2.16 to 4.9). By replacing the conventional λ/4-line with these dual-band lines, the desired dual-band Wilkinson power dividers can be realized. A power divider working at 1.8 / 5.8 GHz is designed using this method. Its measured performance verifies the design concepts.
