| 摘 要： | 研究地网对垂直偶极子天线辐射特性的影响。建立了该天线的仿真模型,采用基于矩量法的仿真软件计算了铺设地网后垂直偶极子天线增益、输入阻抗、最大辐射仰角、3 dB波瓣宽度等辐射特性。结果表明,地网中心偏离天线振子正下方0.75λ时能显著提高天线的增益,改变地网大小和铺设密度也能在一定程度上提高天线的增益。

| Abstract: | The influence of ground screen on vertical dipole antenna was studied.The model of the antenna was established,and the radiation characteristics of the antenna such as gain,impedance,elevation angle of the main lobe,3 dB beam width,were calculated by means of antenna simulation software based on the moment of methods(MOM).The results indicate that when the ground screen is put 0.75 wave-lengths away from the dipole,the gain of the antenna will increase significantly.Increasing the size and the density of the ground screen can also improve the gain of the antenna on a certain extent. |
