1、摘要在现在无线通信产业的飞速发展下,无线通信行业正遍布我国的各个领域,并且竞争也越来越激烈,而作为移动通信系统中通信终端的天线要求也就越来越高。伴随着无线局域网中各项标准的出台,因此,研制可同时适用于多个频带内的天线成为天线的设计的要求。本文提出了一种应用WLAN/WiMAX通信系统的新型双频带印刷天线。通过在微带板蚀刻对称的叉子形辐射贴片和寄生贴片,仿真设计了一款双频带印刷天线结构,借助于仿真软件对天线进行优化设计,使天线能覆盖2.4/5.2/5.8GHzWLAN和5.5GHz频带,并对其进行了测试。结果表明,测试结果和仿真的结果一样
2、,并且在带内拥有良好的全向辐射特性。论文共分为五个部分。首先,论文简单介绍了无线局域网的基本概念,在了解了无线局域网的的基本知识后讨论了印刷天线发展情况,最后简单叙述了本次用的三维仿真软件。其次,详细地回顾了天线的基本理论,包括天线的基本电参数,天线单元的馈电方法等等。接着,介绍了WLAN/WiMAX双频带印刷天线的特点和设计特点以及设计要求。然后介绍了应用于WLAN/WiMAX双频带印刷天线仿真的流程的具体步骤。最后,论文总结了全部工作,并对未来相关研究工作做了适当展望。【关键词】WLAN/WiMAXHFSS双频对称叉子型ABSTRA
