Abstract

This paper introduces a novel approach to create notch band filters in the front-end of ultra-wideband (UWB) communication systems based on electromagnetic bandgap (EBG) structures. The concept presented here can be implemented in any structure that has a microstrip in its configuration. The EBG structure is first analyzed using a full wave electromagnetic solver and then optimized to work at WLAN band (5.15-5.825 GHz). Two UWB passband filters are used to demonstrate the applicability and effectiveness of the novel EBG notch band feature. Simulation results are provided for two cases studied.

摘要

本文提出了一种在超宽带（UWB）通信系统前端基于电磁带隙（EBG）结构创建陷波带滤波器的新方法。这里提出的概念可以在任何具有微带结构的结构中实现。首先使用全波电磁求解器对 EBG 结构进行分析，然后对其进行优化以在 WLAN 频段（5.15-5.825GHz）工作。使用两个 UWB 通带滤波器来演示新型 EBG 陷波带特性的适用性和有效性。提供了两种情况的仿真结果。
