Calculating E and H-field on the aperture of the antenna in CST

[sswh2]

I want to calculate E-field and H-field on the aperture of my antenna in CST. Then I want to export those E-Field and H-field data in cst. So which option in cst I use to calculate E and H field and export the data? Kindly help me out. Thanks in advance!

Not a perfect answer but maybe a solution; also this answer considers using VBA script, and recommends using another program like matlab or python for processing the data.

If I understand you correctly you want the E and H fields ON the antenna (and dont care about the ones outside). If not your question seems trivial; check out monitores and export options on youtube or similar. There should be plenty tutorials.

Possible solution using vba:
Using the Solid object, use the functions
(GetNumberOfShapes)
(GetNameOfShapeFromIndex)
GetAnyFaceIdFromSolid
GetNumberOfPoints
IsPointOnAnyEdgeOfShape

To find the points which is on the edge. The functions in paranthesis can help get the names correctly of the object(s).

Then download the E and H fields using the asciiExport (the points and the field values will both be given).

Then loop the points on the edge and extract the ones matching the exported E and H fields. This is easiest done via matlab or python in my opinion.
