I drew an antenna shown in the attached file, however I don't get a symmetric H-field on the surface of the cylinder. I think I didn't assign the current excitation properly. If you can figure out what the problem is, please inform me.
Now I've changed the shape of the antenna, and the new simulation can be found in the attachment. I converted the curved shapes into not curved ones for the antenna. However, I cannot assign a current excitation on the antenna now.
I was to assign a current excitation on the vertical part of the antenna, but I solved this problem when I deleted the unite function of these 4 cylinders which make the antenna.
However, now I'm confused about the mesh plot of the antenna. When I look at it, I don't see triangles as I'm supposed to. Is the mesh plot of the antenna proper, or is there a way for me to correct it if it's wrong?
