摘要

本文对增强增益的三波段插入馈电矩形微带贴片天线进行了仿真和实验研究。该天线覆盖ISM/WLAN (2.45 GHz)、WiMAX (3.5 GHz)和固定移动(4.65 GHz)频段。天线的频带数量从1个(中心频率2.45 GHz)增加到3个(中心频率2.45、3.5和4.65 GHz)，对应于ISM/WLAN、WiMAX和固定移动业务，方法是在馈线上沿辐射边缘引入两个矩形槽和一个寄生元件。在最佳距离的天线上方放置一个层板以增加组合的增益。模拟的天线在目标频率范围内的输入特性、辐射方向图和增益与相应的实验结果进行了比较。采用Ansys高频结构模拟器(HFSS)软件进行仿真研究。

Triple-band microstrip patch antenna with improved gain

In this paper, simulation and experimental studies of triple-band inset-fed rectangular microstrip patch antenna with enhanced gain are presented. The proposed antenna covers ISM/WLAN (2.45 GHz), WiMAX (3.5 GHz) and fixed mobile (4.65 GHz) frequency bands. The number of frequency bands of the antenna is increased from one (with centre frequency of 2.45 GHz) to three (having centre frequencies of 2.45, 3.5 and 4.65 GHz) corresponding to ISM/WLAN, WiMAX and fixed mobile services by introducing two rectangular slots along the radiating edges and a parasitic element to the feed line. A superstrate is placed above the antenna at optimum distance to increase the gain of the combination. The simulated input characteristics, radiation pattern and gain of the antenna over the frequency range of interest are compared with the respective experimental results. The simulation studies were carried out using Ansys' High Frequency Structure Simulator (HFSS) software.
