摘要
建立了2.4 GHz单极天线的电磁辐射特性仿真模型,分析了天线的远场辐射方向图、辐射效率、实际增益等性能参数特性,研究了天线长度和高度与电磁辐射的关系.根据仿真的远场辐射特性与近场的对应关系设计了印刷单极天线,实测了其近场辐射特性.仿真和实验结果表明:所设计的天线具有最优的电磁辐射特性,为实际2.4 GHz天线设计提供了理论依据和实验指导.
The simulation model of the electromagnetic radiation characteristics of the 2.4 GHz monopole antenna is constructed, and the radiation characteristics such as far-field radiation direction, radiation efficiency, and actual gain are analyzed. Additionally, the variation relationship between the length and height of the antenna and the electromagnetic radiation characteristics is disserted. The print circuit board of the monopole antenna is manufactured and the near-field radiation characteristics are practically measured according to the simulation results. The simulation and experimental results indicate that the devised antenna has the best performance of the electromagnetic radiation. The work can provide the theoretical basis and the experimental conduction for the real 2.4 GHz antenna design.
