Abstract

A new class of broadband microstrip filters for Ultra Wide Band (UWB) applications is proposed. In the design, different stages of parallel-coupled microstrip line and other stages with a Modified Complementary Split Ring Resonator (MCSRR)-a concept proposed here for the first time-are adjusted to obtain the desired response with broadband, sharp rejection, low insertion loss, and low return loss. Full wave simulation results as well as measurement results from fabricated prototypes are presented, showing good agreement. The proposed technique offers a new alternative to implement low-cost high-performance filter devices, applicable to a wide range of communication systems.

摘要

本文提出了一种用于超宽带（UWB）应用的新型宽带微带滤波器。在设计中，对并联耦合微带线的不同级以及采用改进型互补分裂环谐振器（MCSRR，此概念首次在此提出）的其他级进行了调整，以获得具有宽带、陡峭抑制、低插入损耗和低回波损耗的所需响应。给出了全波仿真结果以及制作的原型的测量结果，二者吻合良好。所提出的技术为实现低成本高性能滤波器器件提供了一种新的选择，适用于广泛的通信系统。
