I think it's quite easy to simulate conformal antenna using CST. CST has bending feature, that is to bend patch antenna that you want on a cylindrical structure. You can read it in the manual guide.
i tried to bend an array of patch antenna, but i got this warning, the mesh staircase model will be filled with PEC. how to tackle this? thanks a lot for the reply
thanks for the reply. yes, i have problem with it as the radiation pattern was bad. i design it based on cst video, using bending structure, and when i zoom in my model, it's like not a smooth cylinder. do you think it's caused by that?
