Creating a Cylindrical / Circular Antenna Array
Create a cylindrical or circular finite antenna array model.
- On the Construct tab, in the Structures group, click the Planes/arrays icon. From the drop-down list, select the Cylindrical/circular array icon.
- In the Radius field, enter the radius of the cylindrical / circular antenna array.
-
Specify the elements in the phi dimension.
- Under Phi dimension, in the Number of elements field, specify the number of array elements.
- Under Phi dimension, in the Specify increment field, specify the offset between the array elements.
-
Specify the elements in the N dimension.
- Under N dimension, in the Number of elements field, specify the number of array elements.
- Under N dimension, in the Offset along Z axis field, specify the offset between the array elements.
-
Specify the element rotation.
- To place the array elements with the same orientation as the base element, clear the Element orientation check box.
- To rotate the array elements sequentially, select the Element orientation check box.
-
In the Label field, add a unique label for the antenna
array.
-
Click the Distribution tab to specify the array
distribution.
- To create an antenna array with a uniform distribution, click the Uniform distribution or calculated from plane wave check box.
- To create an antenna array where the distribution is calculated from the plane wave (if a plane wave is present in the model), click the Uniform distribution or calculated from plane wave check box.
- To create an antenna array with a specified excitation for each element,
clear the Uniform distribution or calculated from plane
wave check box.Note: When specifying each element, take note of the array element indexing.
- To specify the magnitude scaling and phase offset manually:
- In the Magnitude scaling field, specify the excitation magnitude for the individual element relative to the base element.
- In the Phase offset (degrees) field, specify the phase offset (in degrees) for the individual element relative to the base element.
- To specify the magnitude scaling and phase offset by importing the
points from file, click Import.
- In the Filename field, browse for the file you want to import.
- [Optional] In the Scale by field, enter a value to scale the points.
- Under Delimiter, click the delimiter type you use in your file.
- Click OK to close the Import points dialog.
- To specify the magnitude scaling and phase offset manually:
