2.9.2   Circular Polarisation for 3D structures

The  button in Radiation tab and Antenna Settings->Polarisation->Circular command from main menu or context menu show 2D radiation pattern results in Circular polarisation.

The  button in Radiation tab and Antenna Settings->2D Chart… command from main menu or context menu invoke Radiation Patterns dialogue for changing 2D radiation pattern parameters.

The XY and Polar charts are available for 2D radiation pattern results.

For 3D structures, the 2D radiation pattern with circular polarisation results contain five curves per each NTF frequency. |Eleft|, <Eleft, |Eright|, <Eright and |Axial Ratio| results. The convention for the left-handed Eleft and right-handed Eright circular polarisation is that for the outgoing wave.

More information regarding circular polarisation and axial ratio definitions can be found in Circular Polarisation and Axial Ratio.

When characteristics at a single NTF frequency are displayed, the status bar presents additional information about radiation parameters.

When the display includes characteristics at more than one NTF frequency, the information about radiation parameters are displayed in the Values pane in the Antenna Parameters column. The Values pane contains information about visible curves such as name, domain, and value under active cursor and other parameters in separated columns, which can be chosen in Select Column dialogue.
