摘要

本文提出了一种用于设计宽阻带、低插入损耗和锐利抑制的微带低通滤波器的新拓扑结构。该滤波器特别适用于无线传感、局部定位和RFID。在这篇贡献中,利用互补分裂环谐振器(csrr)的概念来提高微波低通滤波器的选择性。为此,首先分析并构建了具有CSRR的阶跃阻抗低通滤波器(SILPF)。讨论了这些结构的性能,并成功地测试了两个制造样机。实验结果表明了该结构的有效性和实用性。

A compact microstrip step-impedance low-pass filter (SILPF) using complementary split ring resonators (CSRRs)
A new topology for the design of microstrip low pass filters (LPF) with a wide stopband, low insertion loss, and sharp rejection is proposed in this paper. This filter is especially relevant for Wireless Sensing, Local Positioning, and RFID. In this contribution, the concept of complementary split ring resonators (CSRRs) is utilized to improve the selectivity of a microwave low pass filter. To this end, a step-impedance low-pass filter (SILPF) with CSRR is first analyzed and then built. Properties of these configurations are discussed, and two manufactured prototypes have been successfully tested. The results show the usefulness and validity of the new structures with high rejection capabilities.
