摘要

介绍了一种用于雷达的低通滤波器的设计。该滤波器的主要模块是缺陷微带结构(DMS)、补偿微带电容器和两个缺陷接地结构(DGS)的组合。所提出的滤波器具有几个理想的特性，如通带内插入损耗低至0.3 dB，抑制带从1.5 GHz到8.3 GHz，衰减超过20 dB，以及锐利截止。此外，所提出的设计具有5.8cm×3.5cm的紧凑尺寸。实验测量结果与仿真结果吻合，验证了DMS/DGS滤波器设计适用于雷达和微波应用。

A novel high-performance dms/dgs low-pass filter for radar applications

This paper introduces the design of low pass filter for radar applications. The main block of the proposed filter is the combination of defected microstrip structure (DMS), compensated microstrip capacitors, and two defected ground structures (DGS). The proposed filter has several desirable features such as low insertion loss of 0.3 dB within the pass band, a wide rejection band from 1.5 GHz to 8.3 GHz with more than 20 dB attenuation, as well as sharp cutoff. Moreover, the proposed design has a compact size of 5.8cm×3.5cm. Experimental measurements of the fabricated filter agree with simulation results, which confirm that the proposed DMS/DGS filter design is suitable for radar and microwave applications.
