本文研究了用于低通滤波器 (LPF) 应用的缺陷接地结构 (DGS) 的准三角形。给出了等效RLC电路模型，并利用参数关系提取了其相应参数。设计和制造了使用所提出的 DGS 模式与开路短截线相结合的 LPF。所提出的 LPF 具有尺寸小、插入损耗低和超宽阻带的优点，从 4 GHz 到 >20 GHz 衰减为 20 dB。等效电路模型和全波电磁体的仿真结果与实测结果吻合良好。 © 2012 Wiley periodicals, Inc.

This article investigates a quasitriangular of defected ground structure (DGS) for low‐pass filters (LPFs) application. An equivalent RLC circuit model is presented and its corresponding parameters are as well extracted using the parametric relationships. The LPFs using the proposed DGS pattern combined with open stubs are designed and fabricated. The proposed LPF presents the advantages of small size, low insertion loss and ultrawide stopband with 20 dB attenuation from 4 GHz to >20 GHz. The simulated results obtained by equivalent circuit model and full‐wave electromagnet show good agreement with the measured ones. © 2012 Wiley Periodicals, Inc.
