以下是一个具体的hfss天线仿真,其中包含参数:
1. 首先在HFSS中创建一个新工程,并选择一个适当的单位系统和频率范围。
2. 接下来,创建一个新的天线模型,并定义其几何形状和材料属性。为了使该模型具有参数化能力,可以使用HFSS中的参数化设计工具来定义各种尺寸和位置参数。
3. 接下来,将适当的边界条件应用于模型,例如将边界设置为自由空间或地面平面等。
4. 然后,在HFSS中设置适当的模拟选项,例如激励类型、端口设置和求解器选项等。
5. 最后,运行仿真并分析结果。可以使用HFSS中的各种分析工具来计算天线的性能参数,例如S参数、辐射图案和增益等。
下面是一个示例代码,其中包含一些参数化的尺寸和位置参数:
