Meshing problem

Hi!
I am trying to simulate two very short dipoles ( I am using two simple discrete ports) in a specific distance from each other. But the problem is that when I am changing the size of meshes, the s21 value changes up to 10 dB. It seems increasing the mesh cell sizes make it worse. I don't understand why increasing the mesh cell size can make it worse. Any idea?

Hello lidaasl,
You did not tell that what software you are using for your simulation and which solver i.e. time/frequency domain? Try to set the meshing on adaptive with 5-6 passes you should get the converge results. If you are using CST, I can check it for you.
