单元间距与单元形状对阵列天线辐射影响研究

内容简介：针对阵列天线辐射的问题，对不同阵元间距与不同阵元形状情况下的阵列天线辐射进行了仿真模拟，得到了阵元间距与阵元形状等因素对阵列天线辐射场分布的影响特征与规律。仿真测试表明，在X波段，辐射范围随着间距增大而变大，随阵元口径增大而增大。研究结果可为新型反射阵列天线的设计提供一定的理论依据和借鉴。

Abstract：As for the issue of radiation of the antenna array, in this paper, we simulate the radiation of array antenna that has different distance of element and different cell shape so that we can have the results that what and how the cell shape of the array antenna and the distance of element influence the radiation. The results of simulation indicate the radiation sphere increases with the increase of element spacing as well as the array aperture when working in the X band. The results of this paper provide necessary theory and guidance for the new reflective array antenna.
