Abstract

A Super Wideband (SWB), compact sized, coplanar waveguide fed monopole antenna having dual-band notch feature has been investigated in this paper. The antenna exhibits an extremely wide impedance-bandwidth of 33.12 GHz (01.19 GHz – 34.31 GHz) and an equivalent fractional bandwidth of 186.59 %. The antenna proposed here, shows dual band-notch features at WiMAX (03.3 GHz - 03.7 GHz) and WLAN (05.15 GHz – 05.85 GHz) bands. The band rejection characteristics, for the WLAN band centered at 05.5 GHz has been obtained by introducing a Split Ring Rectangular Resonating Structure (SRRRS) at the lower section of the elliptical radiator. A Defected Spiral Microstrip Structure (DSMS) has been introduced in the feed line segment for obtaining a second band-notch for the WiMAX band centered at 03.5 GHz. The dimension of the whole structure is $W\ x\ L = 20 \times 22\ \mathrm{mm}^{2} = 0.079 \lambda_{\mathrm{o}} \times 0.087 \lambda_{\mathrm{o}}\ \mathrm{mm}^{2}$. The proposed antenna is applicable for Wireless Personal Area Network (WPAN) based communications.

一种新型、紧凑、多带陷波、超宽带无线个人区域网络天线的设计与分析

本文研究了一种具有双频陷波特征的超宽带、紧凑尺寸的共面波导馈电单极天线。该天线具有33.12 GHz (01.19 GHz - 34.31 GHz)的极宽阻抗带宽和186.59%的等效分数带宽。本文提出的天线在WiMAX (03.3 GHz - 03.7 GHz)和WLAN (05.15 GHz - 05.85 GHz)频段显示双带陷波特性。通过在椭圆辐射器的下半部分引入裂环矩形谐振结构(SRRRS)，获得了以05.5 GHz为中心的无线局域网的带抑制特性。在馈线段中引入了一种缺陷螺旋微带结构(DSMS)，用于获得以03.5 GHz为中心的WiMAX频段的第二带陷波。整个结构的维数为$W\ x\ L = 20 \乘以22\ \mathrm{mm}^{2} = 0.079 \lambda_{\mathrm{o}}\ \mathrm{mm}^{2}$。该天线适用于基于无线个人区域网络(WPAN)的通信。
