Simulation Design of Array Electromagnetic Vibrator Combined Ultra Wide Band Antenna

Abstract

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 $\lambda/4\sim\lambda/2$.
