How to use an imported antenna farfield as a source

Dear Antenna Toolbox community,

I'm looking for any good tutorial or suggestion on how to import an antenna farfield (e.g. a GRASP file) and then use it as a source for a em simulation. For an example, I'd like to import the farfield of a custom horn antenna (designed and simulated with a different EM solver, not Antenna toolbox) and use it to illuminate a parabolic reflector or reflectarray (created with Antenna toolbox commands).

Where could I find a good, clear and detailed tutorial to do that? So far, I've not been able to find it.

Thank you very much,

Andrea

Hi,

As per my understanding, you want to know how to use imported data and use it as a source in Antenna toolbox.

You can use measuredAntenna to import your data.

For example,

ms=measuredAntenna 

ms = 
  measuredAntenna with properties:

              E: [0.1000 0.1000 0.1000]
      Direction: [0 90 100]
    PhaseCenter: [0 0 0.0750]

ant=reflectorParabolic('Exciter',ms)

ant = 
  reflectorParabolic with properties:

        Exciter: [1×1 measuredAntenna]
         Radius: 0.1500
    FocalLength: 0.0750
     FeedOffset: [0 0 0]
           Tilt: 0
       TiltAxis: [1 0 0]
           Load: [1×1 lumpedElement]
     SolverType: 'PO'
