摘要

本文利用改进的电磁带隙对双频陷波超宽带(UWB)天线进行参数化研究。电磁带隙(EBG)包括两个条带补丁和一个相对于地的边缘定位通孔，用于双陷波带。为了更好地了解EBG特性及其对24 × 31 mm2双陷波带小正方形超宽带天线陷波带的影响，利用HFSS软件进行了研究。天线工作在回波损耗(s11< -10dB) 3.2 ~ 12.3 GHz范围内。仿真结果表明，实现了WLAN和ITU分别对应的4.57 ~ 4.99 GHz和7.96 ~ 8.32 GHz的陷波带。此外，本文还研究了场线与EBG之间的间隙距离以及通孔相对于地的位置对陷波带中心频率调谐的影响。该天线可以被认为是任何必须避免窄带干扰的超宽带应用的良好候选者。研究为超宽带天线陷波技术中EBG结构沿场线的最佳放置位置提供了思路。

Parametric Study and Analysis of Modified Electromagnetic Band Gap in Frequency Notching of Ultra-Wide Band Antenna

This paper presents parametric study of dual band notch ultra wideband (UWB) antenna using modified electromagnetic band gap. The Electromagnetic Band Gap (EBG) comprises of two strip patched and an edge-located via with respect to ground for dual notch band. The study was presented in order to have an improved knowledge of EBG characteristics and its effect on the notching band of a small squared ultra wideband antenna of size 24 by 31 mm2 dual band notch using HFSS software. The antenna operates within the return loss (s11< -10dB) 3.2 to 12.3 GHz. The simulation results show that the notched band between 4.57 – 4.99 GHz and 7.96 – 8.32 GHz corresponding to WLAN and ITU respectively was achieved. The effect of gap distance between the field line and EBG was demonstrated as well and the position of via with respect to the ground as a means for notched band centre frequency tuning. The antenna could be considered a good candidate for any UWB applications that must avoid narrow band interference. The research gives ideas on the best placement position of EBG structure along field line in UWB antenna frequency notching technique.

期刊介绍： "International Journal of Engineering Research in Africa" is a peer-reviewed journal which is devoted to the publication of original scientific articles on research and development of engineering systems carried out in Africa and worldwide. We publish stand-alone papers by individual authors. The articles should be related to theoretical research or be based on practical study. Articles which are not from Africa should have the potential of contributing to its progress and development.
