Abstract

A dual-band planar printed monopole antenna for wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications are presented. The proposed antenna is designed on inexpensive FR4 substrate having dielectric constant 4.4 and thickness 1.6 mm, which covers WLAN 2.4 GHz (2.4 GHzȓ2.5 GHz), WiMAX 2.5 GHz (2.5 GHzȓ2.69 GHz), WiMAX 3.5 GHz (3.3GHzȓ3.6GHz), HIPERLAN1 5.2 GHz (5.15 GHz-5.35 GHz), and HIPERLAN2 5.8 GHz (5.725 GHzȓ5.825 GHz). The proposed antenna mainly consists of inverted U-shaped strip, inverted L-shaped strip and modified ground plane. The modified ground plane was introduced to enhance the performance of the proposed antenna. It is found that the proposed antenna can meet the demands of WLAN and WiMAX systems by having bandwidth of 1.4 GHz (2.25-3.65 GHz) for the lower band and 2.13 GHz (4.37 GHzȓ6.5 GHz) for the upper band defined by -10dB reflection coefficient. The radiation patterns and gain characteristics are also presented. Due to compact size, the proposed monopole antenna may well work as an internal antenna in a portable device for WLAN/WiMAX operations.

用于WLAN/WiMAX/HIPERLAN应用的微带线馈电双带印刷单极天线

提出了一种用于无线局域网(WLAN)和全球微波接入(WiMAX)应用的双频平面印刷单极天线。该天线设计在介电常数为4.4、厚度为1.6 mm的廉价FR4衬底上，覆盖WLAN 2.4 GHz (2.4 GHzȓ2.5 GHz)、WiMAX 2.5 GHz (2.5 GHzȓ2.69 GHz)、WiMAX 3.5 GHz (3.3GHzȓ3.6GHz)、HIPERLAN1 5.2 GHz (5.15 GHz-5.35 GHz)和HIPERLAN2 5.8 GHz (5.725 GHzȓ5.825 GHz)。该天线主要由倒u形带、倒l形带和改进接地面组成。为了提高天线的性能，引入了改进的地平面。结果表明，采用-10dB反射系数定义的下带带宽为1.4 GHz (2.25-3.65 GHz)，上带带宽为2.13 GHz (4.37 GHzȓ6.5 GHz)，可以满足WLAN和WiMAX系统的需求。给出了辐射方向图和增益特性。由于尺寸紧凑，所提出的单极天线可以很好地作为便携式设备中的内部天线用于WLAN/WiMAX操作。
