Strange thing with CST
Hi,
I'm simulating some microstrip antennas in CST. I'm trying to put ground plane to all my designs from the same metal of patch.
I know the boundry condition Et=0 do the same. I prefer to put as well.
Anyway, I tried to delete the ground plane and re-draw it today.
Only delete and re-draw with same dimensions and same material.
I discovered that mesh cells gone to half and there is new results. The important thing that there is shift in s11 notch about 0.3 GHz also.
Any idea about why ???????????
