【摘要】 短距离无线通信网可以随时随地的进行数据通信,减少了对有线连接的要求,提高了网络的灵活性,并且因其可移动性、组网灵活性、应用范围的广泛性和传输速度快等优点,使得在当前个人家庭和办公环境逐渐开始广泛的应用。 对于微带天线的研究已经有了二十多年,因为其特殊的优点:体积小、重量轻、成本低、平面结构、易于和集成电路集成等,相同结构的微带天线可以组成微带天线阵,可以获得更高的增益和更宽的带宽。微带天线得到愈来愈广泛的重视,尤其在当前,随着短距离无线通信网飞速发展,微带天线的优点越来越明显。因此对微带天线的进一步研究显得十分重要。 本文主要针对微带天线在短距离无线通信网络中的应用,对微带天线的特性进行了理论分析。特别针对微带天线在蓝牙通信和超宽带通信系统中的应用,分别设计一种微带天线,并且通过利用微波EDA软件,对设计参数进行了仿真和优化,最后对设计的天线进行了加工测试,得出的天线的主要参数基本满足设计要求。本文不但设计了两种新型的微带天线,还讲述了微带天线的分析和设计过程,为微带天线在分析和设计方法提供了一个新的思路。 本文主要分为6章,第一章绪论,介绍了论文研究的相关内容;第二章重点讨论了UWB这种新的通信技术;第三章重点论述了微带天线的基本原理,以及设计和分析方法;第四章简要的讲了用有限元法分析微带天线的方法;第五章论述了两种天线的设计、仿真和测试过程,给出了相应的参数;第六章是结论以及课题还要继续改进的方向。更多还原

【Abstract】 Short-range Wireless Communication can not only send information anywhere and anytime, but reduce the demand for wire link, and it improve the functional agility of communication system. Short-range Wireless Communication has many advantages, such as flexible removability、 agility、 universality and high rate, so it will be used in house and official field more and more universal.The theory of microstrip radiators was proposed for more than twenty years,. Microstrip antennas have some principal advantages compared to conventional microwave antennas, such as lightweight, low profile, planar configurations, low fabrication cost , easy compatibility with modular designs and so on. Microstrip antennas will ultimately replace conventional antennas for most applications. Especially, with the development of Short-range Wireless Communication, more and more mobile communication equipments need lightweight, flexible, and low profile antennas. So microstrip antennas show their advantages in all kinds of communication environment. It is very important to go on studying the characteristics of microstrip antennas. The paper aims at the application of microstrip antennas in Short-range Wireless Communication and analyzes the theory of microstrip radiators. Two new styles of microstrip antennas were designed for the application of bluetooth communication system and Ultra-wide Band radio. In order to prove the validity of the design for the two antennas, the microwave EDA software was used to simulate and optimize the parameters of antennas. Finally two kinds of antenna models were made and the key parameters of microstrip antennas were measured with VNA. The paper not only shows the parameters of two new styles of microstrip antennas, but provides the method for the analysis and design of microstrip antennas.The paper consists of six chapters. The first chapter is preface .The second chapter discussed the UWB radio. The third chapter specified the theory of microstrip radiators. The fourth chapter discussed the FET in brief. The fifth chapter is the core of this paper. It showed the process of design, analysis and measure of microstrip antennas; in detail. The last chapter is the summarization of the work that we have done. The advice for the future work was presented.更多还原
