[Moved] trying to design rectangular patch microstrip antenna

[Chorintan Prabelia]

hello, i have a problem when i design rectangular patch antenna for GPS, there are words that say

Defined reference frequency for open boundary condition (2 GHz) is larger than the lowest relevant system frequency (monitor at 1.57542 GHz).
Please check open boundary settings to ensure accurate monitor results for the lowest frequency of interest.
The monitor surface-current (f=1.57542) is not supported and will be ignored. Please define an 'H-Field and Surface current monitor' instead.

and i'm so confused when i try to feed with coaxial probe there is error,

Post processing terminated abnormally.

i need help :sad::sad::sad::sad::sad:

Hi there,

I'm assuming you are using CST MWS. You need to go to "open boundaries" settings and check that it is set to center frequency and monitors.
