CST偶极子天线仿真,半波振子天线

一。本文使用CST仿真频率为1GHz的偶极子天线,使用2013版本。仿真的步骤为

1。选择一个CST的天线工程模板

2。设置好默认的单位

3。设置背景的材料(空气腔等)

4。建模,画出天线的结构

5。设置频率

6。设置边界条件

7。定义激励

8。远场设置

9。设置远场结果分析的模板

10。选择合适的求解器

11。分析结果

二。具体实现。

  1. 1。新建工程,依次选择Microwave&RF—>Antennas--->wire--->Integral Equation,然后选择默认使用的单位,如下图所示,最后点击Finish.

I have given you authority to trample on snakes and scorpions and to overcome all the power of the enemy; nothing will harm you. However, do not rejoice that the spirits submit to you, but rejoice that your names are written in heaven.”

– Luke 10:19-20 (NIV)
