Changing the Dielectric Constant of a Microstrip Patch Antenna in Antenna Toolbox

Hi all, I'm trying to reate a Patch Antenna using the Antenna Toolbox. I've been using tutorials, such as the ones found here: http://www.mathworks.com/help/antenna/examples/fmcw-patch-antenna-array.html
All the tutorials I can find mention that "The dielectric substrate is air." How do I change the dielectric constant to a different value (say 3.5 for the Rogers board I'm using), since that can have a large effect on the radiation pattern?

This is the documentation page for dielectrics. Hope this helps. Please do not hesitate to ask more questions regarding dielectrics if the documentation is not clear.

That thing is in 2017 or versions after 2016a. Most of us have 2013 or 2015(the more fortunate ones'), so how to get it done in 2015 atleast. Thanks

Hi Abubakar,
Currently it does not seem like there is a way to use a different value for the dielectric constant. I work for MathWorks and I have forwarded this request to the appropriate product team.

When using the Antenna designer tool you can edit the substrate befor uploading the antenna in the workspace. This is 'Air' by default
That worked for me
