内容简介：为提高带通滤波器的选择特性，文章基于逆开口谐振环（CSRR）的构造思路，首先提出一种菱形逆开口谐振环（DSCSRR），并对其左手特性加以证明；然后详细研究了改变其结构参数对DSCSRR传输特性的影响程度；最后设计了一款基于DSCSRR带通滤波器并对所设计的滤波器进行了实物加工和实验测量，测量结果与仿真结果表明，所设计滤波器的中心频率为4．02GHz，选择特性为170dB／GHz，带内抑制小于15dB。该新型滤波器不仅具有选择特性高，而且具有体积小、设计简单等优点。
Abstract：Inspired by CSRR （complementary split ring resonator）, a novel structure named DSCSRR （diamond shaped complementary split ring resonator） was proposed in this article to enhance the selectivity of bandpass filter. And then its left-handed characteristics were presented and its transmission characteristic was studied. In the last a bandpass filter based on DSCSRR was designed and fabricated. The agreement of simulation and measurement results indicates that the proposed filter＇ s working frequency is 4.02 GHz, and its selectivity is 170dB/GHz, and insertion loss 15dB. The proposed filter have some advantages such as high selectivity, simple in design, and also compact in size.
