Hi Steven,

Thank you for reaching out to us and we appreciate your patience. 

I have some observations based on your post – 

 

  1. Is the antenna source placed at the focal point of the lens?
  2. What are the material properties of PLA that you are using?
  3. The top surface of the lens appears to be faceted. Is this intended?
  4. Did you take care of the reflections of the lens falling on the source?

Kindly check these to see if you can get improvement in your results.

Best regards,
Praneeth.
