Abstract

In this paper, a microstrip line-fed rectangular-shaped ultra-wideband (UWB) antenna offering triple-band notch characteristics is proposed. The notching was done primarily to provide rejection for Wi-Max (3.3-3.7 GHz), WLAN2 (5.15-5.825 GHz), and ITU (8.025-8.4 GHz) through the combination of slots and a modified electromagnetic band gap (M-EBG). The antenna was simulated using HFSS and CST modelling tools. The antenna was able to notch three frequencies from narrow band communication systems (Wi-Max, WLAN2, and ITU), causing interference within the UWB band. The gain of the system over the operating frequency, the current distributions, and the impedance covered were studied to assess the effectiveness of the antenna. The proposed antenna is simple and compact, with a total antenna size of 19 mm by 24 mm and a wide bandwidth (3.2 to 12.5 GHz). Satisfactory results have been obtained when its performance was analyzed. A stable radiation characteristic is observed with a radiation efficiency of 94% when operating at a UWB resonant frequency of 6.85 GHz with a total gain between -10 dB and 5 dB within the range of the frequency band of 3.2 to 12.3 GHz.

三波段缺口超宽带天线的研制

本文提出了一种具有三频带陷波特性的微带线馈矩形超宽带天线。切槽主要是为了通过槽和改进的电磁带隙(M-EBG)的组合为Wi-Max (3.3-3.7 GHz)、WLAN2 (5.15-5.825 GHz)和ITU (8.025-8.4 GHz)提供抑制。采用HFSS和CST建模工具对天线进行仿真。该天线能够从窄带通信系统(Wi-Max, WLAN2和ITU)中截取三个频率，从而在UWB频段内产生干扰。研究了系统在工作频率上的增益、电流分布和所覆盖的阻抗，以评估天线的有效性。该天线结构简单紧凑，天线总尺寸为19mm × 24mm，带宽为3.2 ~ 12.5 GHz。对其性能进行了分析，取得了满意的结果。在3.2 ~ 12.3 GHz频段，工作在6.85 GHz的超宽带谐振频率下，总增益在-10 ~ 5 dB之间，辐射效率为94%，具有稳定的辐射特性。

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.
