# Circular / Cylindrical Layout

This option defines the finite antenna array with a circular or cylindrical distribution.

## Parameters:

- Radius
- The radius of the circular/cylindrical antenna array.
- Number of elements along Np
- The number of finite antenna array elements along the Np/ $\varphi $ direction.
- Number of elements along Z axis
- The number of finite antenna array elements along the Z axis.
- Angle between elements (Np)
- The angle between the respective finite antenna array elements.
- Offset along Z axis
- The distance between the finite antenna array elements along the Z axis.
- 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.
