本文介绍了一种具有互补分裂环谐振器（csrr）的紧凑型基板集成波导（SIW）功率分配器的研制。所提出的SIW功率分配器被设计用于无线局域网（WLAN）应用的s波段频率。将两个反向排列的csrr合并到SIW表面，旨在产生功率分压器的滤波效果，用于抑制不需要的信号。通过仿真对功率分配器的物理参数进行了一些参数化研究，得到了紧凑的功率分配器设计。在参数化研究的基础上，将带csrr的SIW功率分压器部署在1.6 mm厚、尺寸为$40\ \text{mm} × 30\ \text{mm}$的FR4环氧树脂介电基片上。从表征来看，所提出的SIW功率分配器显示出在2.4 GHz频率下工作的能力，在阻带区域的抑制率大于20 dB，适合所需的应用。
In this paper, the development of compact substrate-integrated-waveguide (SIW) power divider with complimentary-split-ring-resonators (CSRRs) is presented. The proposed SIW power divider is designed to work at S-band frequency for wireless local area network (WLAN) application. Two reversely arranged CSRRs incorporated into the SIW surface are intended to produce filtering effect of power divider useful for suppressing unwanted signals. Some parametric studies upon the physical parameters are carried out through simulation to obtain the compact design of power divider. Based on parametric studies, the proposed SIW power divider with CSRRs is then deployed on a 1.6 mm thick FR4 epoxy dielectric substrate with the size of $40\ \text{mm}\times 30\ \text{mm}$. From the characterization, the proposed SIW power divider shows capability to work at the frequency of 2.4 GHz with the rejection rate more than 20 dB at the stopband area which is suitable for the desired application.
