摘要

提出并设计了一种椭圆函数集总元低通滤波器。该滤波器的截止频率为1GHz，衰减极为1.06 GHz，具有良好的锐度系数和可忽略的通带插入损耗。最后，采用螺旋形缺陷微带结构(DMS)的50欧姆微带线去除约3.2 GHz处的杂散传输峰，提高了衰减带宽。所设计的滤波器可用于现代微波和毫米波通信系统。

Design and performance improvement of lowpass filter by using Defected Microstrip Structure

In this paper, an elliptic-function lumped element lowpass filter is proposed and designed. The proposed LPF provides cut-off frequency at 1GHz and attenuation pole at 1.06 GHz with good sharpness factor and negligible passband insertion loss. Finally, the attenuation bandwidth is improved by the removal of spurious transmission peak which is occurs at about 3.2 GHz using 50 ohm microstrip line with spiral-Shape Defected Microstrip Structure (DMS). The designed filter is useable in modern microwave and millimeter wave communication systems.
