your work indicated that the fractal aspect didn't help.

I think the thickness is the key part... more triangles means more effective surface area. If your thickness was thicker or your top-down area was less, the fractal antenna would be remarkably better. Please see below.

What do you think?

Thank you in advance for your time and good job with the site!

If you increase the fractal thickness, the bandwidth will improve, that is true. However, the exact same thing happens with the simple dipole antenna. So the goal was to do an apples to apples comparison and compare a simple printed dipole and a fractal, to determine if improvement is made.

You could extend the study and do it in 3d, but I suspect strongly the results would stay the same as I increase the thickness of the dipole
