6.3.1   Exporting 3D radiation pattern

3D Radiation Pattern window allows exporting the 3D radiation pattern to the *.an3 file with  button in Export/Import tab and Export Results->Save 3D Radiation Pattern… command from main menu or context menu.

Example 1: format of *.an3 file with 3D radiation pattern

Remarks:

·         Field values are always saved in Directive scaling, so Gain scaling factors are given in the header.

·         Ef denotes Efficiency calculated for the radiation pattern.

·         S11 denotes S₁₁ calculated for the input port (it is used for scaling).

·         lktheta and lkphi denote the number of steps along Theta and Phi angles, respectively. Span of these angles is fixed: 0 ≤ Phi ≥ 360, 0 ≤ Theta ≥ 180.

·         Radiation pattern values are saved line by line using the following routine:

for(k=0;k<lktheta;k++)

      for(i=0;i<lkphi;i++) fprintf(…)

6.3.1.1    Exporting 3D radiation pattern to SAT file

3D Radiation Pattern window allows exporting the 3D radiation pattern to the *.sat file with  button in Export/Import tab and Export Results->Export to SAT… command from main menu or context menu.

6.3.1.2    Exporting 3D radiation pattern as a picture

The displayed 3D radiation pattern can be exported as a picture to *.bmp, *.jpg, or *.png file format by using  , ,  or  buttons from Export/Import tab and Export Results->Export to… or Export Results ->Save Picture… commands from main menu or context menu. The picture quality (the default is the best quality) for JPG format can be set in the View tab in the Preferences dialogue.

The displayed 3D radiation pattern can be copied to the Clipboard using  button from Export/Import tab and Export Results->Copy to Clipboard command from main menu or context menu.
