How to add a ground plane to a linearArray?

The support article below says that you simply set parameter 'GroundPlaneWidth' to whatever you want, however this property is protected in linear array?

To clarify, I have an array of monopoleRadials that I want to place over an infinite ground plane

Hi Colton,

I am attaching a small piece of code for the reference and I think this should work for you.

lin = linearArray('Element',monopoleRadial)
r = reflector('Exciter',lin,'GroundPlaneWidth',inf)

I hope this helps.

Cheers

Thank you! I did a similar workaround with a conformalArray because I need individual control of the linear array weights. I think both methods work.

Hi Shashank, I actually just tried your code and it gives me the error

"linearArray cannot be set as an Exciter for the antenna"

I recommend for anyone else trying to do this to use conformal array with multiple elements of your antenna, and a reflector with a very small dipole. The results I got seem reasonable
