摘要

为了研究超宽带平面阵列的AVSWR特性，利用商用软件对由周期边界模型和天线阵列组成的全金属Vivaldi天线进行了仿真。将AVSWR的周期边界计算结果与通过计算单元间耦合得到的阵列计算结果进行了比较。对比结果表明，中心单元的特性更接近理想周期边界的结果，当阵列规模足够大时，利用周期边界模型对阵列天线进行优化是可行的。

Analysis of Characteristics of Ultra-Wideband Planar Array Based on Design of Array Antenna

In order to study the AVSWR characteristics of ultra-wideband planar array, the simulations of all-metal Vivaldi antenna, which consist of the periodic boundary model and the antenna array, are finished through the commercial software. The AVSWR's result of the periodic boundary is compared with the result of the array which is obtained by calculating the coupling between elements. The result of comparison shows that the characteristics of central elements are closer to the result of ideal periodic boundary and it is feasible to use periodic boundary model to optimize the array antenna when the array's scale is large enough.
