摘要
天线辐射特性是无线传感网中的重要参数,但由于其受众多因素影响,同时辐射特性测量是专业、昂贵且费时的过程,因此该参数常被简化或忽视。针对该问题,设计面向无线传感网的天线自动测量系统和数据处理程序,用于实现天线辐射特性的快速测量和数据处理。在此基础上对无线传感网中14种典型天线在不同平面上的辐射特性,以及金属平板对天线方向性图的影响进行测量分析和讨论,总结各天线特点及目标应用场景。上述研究可为针对不同应用的无线传感网系统天线选择和安装提供参考和建议。
Antenna radiation characteristics of the antenna are important parameters in Wireless Sensor Networks( WSNs),but they are often overlooked or simplified because the antenna radiation characteristics measurement process is professional,expensive and time-consuming,and the characteristics are affected by many parameters. Aiming at this problem,this paper presents an automatic antenna measurement system and data processing program for WSNs,which can quickly and easily implement measurement and data processing of the antenna radiation characteristics. Furthermore,radiation characteristics of fourteen typical antennas in WSNs on different planes and the influence of metal planes on antenna directivity are measured and analyzed. At last,the characteristics and target application scences of all antennas are discussed. This study is expected to provide suggestions and references for antenna selection and installation in WSNs for different applications.
