| Abstract | 本文通过对微带馈电 Vivaldi 天线进行仿真，对 Vivaldi 天线辐射段参数不同尺寸进行模拟，分析了参数对天线远场方向图和回波损耗的影响。对于相控阵馈源的具体应用，在不改变 Vivaldi 天线其他参数的情况下，采用扼流槽加载技术对微带馈电 Vivaldi 天线进行改进，并对两者的仿真结果进行对比。结果表明扼流槽加载技术可以明显改善Vivaldi 天线的低频端增益和旁瓣。仿真结果对于反射面天线相控阵馈源的阵元结构的改进具有一定的意义。 |
| Other Abstract | In this paper, the microstrip fed Vivaldi antenna is simulated, and the different sizes of Vivaldi antenna radiation segment parameters are simulated, and the effects of parameters on the antenna far-field pattern and return loss are analyzed. For the specific application of phased array feed, without changing other parameters of Vivaldi antenna, the microstrip feed Vivaldi antenna is improved by using choke slot loading technology, and the simulation results of the two are compared. The results show that the choke slot loading technique can significantly improve the low frequency gain and sidelobe of Vivaldi antenna. The simulation results have some significance for the improvement of the array structure of the phased array feed of the reflector antenna. |
