Antennas & Arrays 02 - Optimization in HFSS Using MATLAB

In the second video I discuss how to communicate between MATLAB and HFSS to setup an optimization environment. I use the U-slot patch antenna as an example to optimize the input matching over 7 parameters. Final results show a bandwidth of 20%. The same technique can be use to design other EM structures. In this case I have used Nelder-Mead optimization since I found it works well for low-dimensional non-linear optimization.
The codes and all simulation files are available on GITHUB at: github.com/AdityaMuppala/HFSS...
Feel free to catch any mistakes and post them in the comments or send me an email at [e-mail].

i have a problem with the costFunc. When running sucessfull, the costFunc display only one the value at -5.0819 with the graph of Iterations. Can you help me fix this problem? Thank you!

Check to make sure you are exporting and importing the correct S11 data.

I need to implement and learn Hfss for antenna design for my project.
Can you please help me.

[@adityavarmamuppala437]

I suggest watching some TH-cam tutorials and reading the HFSS getting started guide. Good luck!

Why not use the built-in optimization feature of HFSS? What't the different?

You have the freedom to use any optimization algorithm of your choice with MATLAB.
