摘要

近年来，大功率超宽带电磁脉冲源技术得到了迅速发展。为了更好地发挥其价值，迫切需要一种大功率超宽带天线来有效辐射电磁能量。本文利用CST微波工作室对电磁振子组合天线进行仿真，确定单天线的尺寸和形状。然后模拟$3\times 3$阵列天线。通过改变天线间距，发现:1;水平面上的波束宽度仅与天线在水平方向上的间距有关;2. 垂直方向上的波束宽度仅与天线在垂直方向上的间距有关;3.天线增益随天线间距的变化而波动，在$\lambda/4\sim\lambda/2$处基本保持稳定。

Simulation Design of Array Electromagnetic Vibrator Combined Ultra Wide Band Antenna

In recent years, high-power ultra wide band electromagnetic pulse source technology has developed rapidly. In order to better exert its value, there is an urgent need for a high-power ultra wide band antenna to effectively radiate electromagnetic energy. In this paper, the CST microwave studio is used to simulate the electromagnetic Vibrator Combined antenna to determine the size and shape of a single antenna. Then simulate the $3\times 3$ array antenna. By changing the antenna spacing, it is found that: 1. The beam width in the horizontal plane is only related to the spacing of the antennas in the horizontal direction; 2. The beam width in the vertical plane is only related to the spacing of the antennas in the vertical direction; 3. The gain of the antenna fluctuates with the change of the antenna spacing, and remains basically stable at $\lambda/4\sim\lambda/2$.
