Isotropic radiator

Hello Professionals,

 

How can I implement an ideal isotropic radiator in FEKO? I want to compare distribution of an electrical field without antenna gain using asymptotic methods. Can you help me with that?

 

Best regards,

Dimon

    An isotropic radiator does not exist and is not available as a source in FEKO. You can approximate it using a radiating antenna source (you can define the pattern to be constant).

    What I usually use and what I would recommend is that you use a electric point source. It radiates a 'donut' radiation pattern. You could use three of them at orthogonal angles to approximate an isotropic radiator (I have never tried that). Usually a single electric point source is sufficient for what I wanted to do in the past.
