RCS simulation does not seem correct

Hi,
I'm simulating a rectangle or circular PEC plate in EMPro to calculate the RCS.
When the frequency of operation is 6 GHz and the dimension of the place is about twice of the wavelength (wavelength=50 mm at 6 GHz and the dimension is 100 mm) the RCS is about -2~-3 dBsm
But when I increase the frequency to 75 GHz (wavelength=4mm) and the dimension is about the wavelength( 4 mm) the RCS increases to -60~-70 dBsm !
I'm wondering that whether I set something wrong in my simulation or the software can not work properly in this frequency or the results is correct?
Would you please help me with this problem?
Thank y'all
