录入：edatop.com 点击：
A custom antenna array is a an arbitrary array of identical elements distributed in 3D space with individual user-specified complex weights. The array is defined in a text file that includes the element positions, voltage amplitude weights, and phases. See Custom Arrays in the Technical Notes for examples of custom array geometry text files.
Note | For custom antenna arrays, phases should be specified in radians. |
1. Click HFSS or HFSS-IE>Radiation>Antenna Array Setup.
The Antenna Array Setup window appears.
2. Under the Array Type tab, select Custom Array Setup.
3. Click the Custom Array tab.
4. Click Import Definition.
The Open dialog box appears.
5. Follow the procedure for opening a file. Select .txt as the file type. When you are finished, click Open.
6. Optionally, review the definition in the text file by clicking View Definition under the Custom Array Setup tab.
7. Click OK.
The array factor will be applied, using the information specified in the text file, when far fields are calculated.
