Multilayered structure CMA
hi! I am simulating multilayered antenna structure, but I not getting accurate modes. I have simulated this antenna using Infinite Ground plane condition but now I want to resimulate it using actual ground plane, I have attached screenshot of the modes and design with a triangular top structure. Can anyone guide me through what mistake I have been doing . One moderator asked me to change meshing, I did that but its of no use because I am getting similar results

These are the modes with Infinite ground plane

It is difficult to say, you may need to try different approaches. You can also try using a finer frequency sampling or a combination of both.

I have tried combination, defined local mesh along with fine meshing. Actually it takes a lot of time for simulation due to large ground. I want to see the difference with infinite and actual large ground. I am getting different results in CST thats why I want to simulate complete design in FEKO so that I can be sure I am doing it right

Sir how You take infinite ground plane and what are the dimensions in X and Y axis in feko?
