Field of View Analysis on Platforms

Is it possible to make FOV (Field of View) analysis on FEKO for the antennas placed on any platform.

Example: I have a phased array antenna that will be placed on any platform. I am curious about automated result for FOV. Does platform block the signal line of sight.

I know that CST has such a property but I don't know about FEKO.

Can you help?

Thanks

Hi Omer,

as far as I know there is no defined workflow for this yet. I have already noted this as a feature request for the development and hope for a timely workaround.

Just thinking: Maybe it would be possible to calculate the farfield pattern of the antenna on the platform and save it as a .ffe or .sph file. This file could then be used in a second model as a point source in the center of a large hollow sphere to see the areas of the sphere that are illuminated. For the sphere you could use RL-GO or PO.

But as I said, this is just an idea.

Best regards,

Torben

Hi @Omer Can DABAK ,

An easy way to perform a FOV analysis is shown in the attached example.

Put an elementary source at the desired position (ideally omnidirectional antenna)
Select the model to be solved with faceted UTD
Select direct rays only (no reflections, no diffractions)
Create a full 3D far field plot
View this in a surface graph and set the colour map such that all which is zero is blue

Note, on my Windows 11 laptop I presently can't change the individual range in cartesian surface graphs (we're investigating...) This probably works for you.

Hope this helps!

Best regards,
Torben
