Performance Optimization of a Wideband Antenna using HyperStudy
Hello,
I have modeled a wideband microstrip patch antenna in FEKO. I want to use HyperStudy to find one optimum value of a design parameter that yields the best bandwidth (i.e., best S11 value over the entire frequency range, say 1 to 3 GHz). I shall be glad if you could please let me know the procedure.
Thanks in advance.

P.S. So far, I have used HyperStudy to find the optimum value of a design parameter to obtain the best S11-value at a single frequency point. I tried using the multi-objective optimization feature (by defining S11 at 31 frequency points manually - please find the attached image) for my current objective of bandwidth optimization, but it resulted in 31 different optimum values of the single design parameter at the 31 different frequency points.

i see a few options that you could try:
1) create a response with the sum or average of your S11 vector, and ask HSt to optimize it, so that in the end all values should be reduced in average
2) use curve area or integral, as the tutorials attached. For example, giving a target curve for HSt, and asking it to calculate the curve difference, and optimize to get as close as possible

Have you found a way to analyse "multiple" points / or curve (IN HST)? i would like to do the same but with radiation pattern to optimize model according to designed Mask (or even lower and upper mask) for few parameters (placed around metallic surface) and try to use DOE/ FIT function to later do more analysis and find the best setup of the antenna around this object.
Regars,
