[SOLVED] more than one antenna in cst (mesh problem)

[phran]

Hi, i have a problem with cst 2011.
I'm trying to simulate two simple patch antennas in open space (@ 2.45 GHz).
The antennas are placed in a room (air) and the distance of the one from the other is about 2 meters.
Now, i need to increase the mesh around the antennas but decrease it in the rest of the free space but i don't know how can i do this.
Can you help me ?
Thank you!

I think you can chose your object and then use
Local mesh properties and Maximum mesh step width to do this.

You can use simple equations, instead of EM simulation:
