摘要

提出了一种在EBG结构地平面上实现微带低通滤波器的新方法。高抑制带宽是通过在地平面上蚀刻圆形EBG图案来实现的。在EBG模式中引入的偏移量进一步提高了抑制带宽。采用基于IE3D模拟器的全波矩量法进行仿真。根据s参数确定的滤波器的特性在更高的频率范围内描述了改进的抑制带宽。

Microstrip Low Pass Filter with Improved Rejection Bandwidth

A novel implementation of microstrip low pass filter is proposed on the EBG structured ground plane. A high rejection bandwidth is achieved by etching the circular shaped EBG pattern on the ground plane. The offset introduced in the EBG pattern further improves the rejection bandwidth. The simulation is performed using the full wave Method of Moments based IE3D simulator. The characteristics of the filter determined in terms of S-parameters depict an improved rejection bandwidth over a much higher range of frequencies.
