摘要
在现代无线通信高速发展的背景下,超宽带无线技术以其优异的性能成为了全世界的研究热点。超宽带滤波器是超宽带通信系统的重要组成部分,其性能将直接对整个系统产生重大影响。本文提出了一种基于微带/共面波导结构的超宽带带通滤波器,并通过嵌入λ/4开路支节实现了在5.8GHz处的陷波特性,可以有效地滤除WLAN信号。实测滤波器的结果与仿真结果基本一致,验证了设计的有效性。
In the context of the rapid development of modern wireless communications,ultra wideband wireless technology has become a research hotspot in the world due to its excellent performance.The UWB filter is an important part of the UWB communication system,and its performance will directly have a signif icant impact on the entire system.This paper proposes an UWB filter based on a microstrip/coplanar waveguide structure,and realizes the notch characteristics at 5.8GHz by embeddingλ/4 open-circuit branches,which can effectively filter WLAN signals.The results of the measured filter are basically consistent with the simulation results,verifying the effectiveness of the design.
