Specifically I have a folded dipole on FR4 that I want to examine with varying substrate thicknesses and properties. I've seen the method in some examples of creating a reflector and setting the Exciter property. However, how do I remove the reflecting surface or change the reflector size independent of substrate? Is the Reflector object a class that can be extended and customized to add this functionality?

Hi Jeff,

The ability to modify the reflector dimensions independently of the substrate does not exist currently. We are working to add this capability in a future release. The use case you have provided is helpful in this regard.

Thanks,

Vishwanath

Jeff,

Thank you. We would love to hear from you. I would recommend the following: https://www.mathworks.com/products/antenna/expert-contact.html

On this website, there are two options. First you can directly enter some basic information and post a message. We can then follow up with you. Second, there is also an option to contact technical support, which would require you to create a service request.

In both cases, please mention that you are following up on a conversation thread from MATLAB Answers.

Hope to hear from you soon.

Warm regards,

Vishwanath

Jeff, Vishwanath,

I was wondering if you found a solution to your problem. Or if there has been a way you found to address this in R2016b. I am in a similar position where I want to model a dipole without a substrate ground plane. Please let me know if there is any solution to the problem, or an alternative method you found. I would immensely appreciate the information.

Best regards,

Jorge Cossio
