Hello,
I have previously used the aperture fields (*.efe and *.hfe files) of a rectangular horn antenna to define an equivalent near-field source (by modeling a rectangular aperture of same dimension as that of the horn antenna). The comparison of the simulated far-field patterns obtained from the real antenna and the equivalent source had excellent agreement.
Now, I want to do the same thing for a circular aperture. For that I've already extracted the aperture fields from a conical horn antenna. However, I am unable to model a near field source which is circular in shape.
Any suggestions are welcomed. Thank you in advance!
Hi @AGirlHasNoName ,
Unfortunately, the approach with cylindrical request with height 0 does not seem to be supported.... So maybe it would be a possibility to wrap the whole horn antenna with a cylindrical or spherical request. Would this be an option in your case?
Best regards,
Torben
