Distribution Follows in *.pre File
This option defines the finite antenna array by specifying the distribution and excitation for each individual element directly in the .pre file.
Figure 1. The FA - Finite array analysis dialog, with Distribution follows in *.pre file selected.
Parameters:
- Number of elements
- The number of antenna array elements specified in the antenna array.
- X, Y, Z coordinate
- Cartesian coordinates for the location of the respective antenna array elements.
- Rotation around X axis (degrees)
- Angle of rotation around the X axis in degrees.
- Rotation around Y axis (degrees)
- Angle of rotation around the Y axis in degrees.
- Rotation around Z axis (degrees)
- Angle of rotation around the Z axis in degrees.
- Element excitation
- If the Uniform distribution or calculated from plane wave option is selected, the array elements will either have a uniform distribution or the distribution will be calculated from the plane wave if a plane wave is present in the model. If the Specify amplitude and phase for each element option is selected, the user can specify the excitation for each element.
- Magnitude scaling
- The excitation magnitude for the respective element is scaled relative to the base element.
- Phase offset (degrees)
- The phase offset in degrees for the respective element relative to the base element.
