Periodic port angular incidence depends on model size

I have a periodic port which generates Hz plane wave. Also, I have periodic conditions with the floquet periodicity. K vector is From periodic port.
When I run the model using the following sizes (height=0.1*wavelength and width=0.2*wavelength) I have reasonable results. Dependence curve is somehow sqrt(cos) function from the angle.
Now the problem is: When I just change model size (let's say height=wavelength and width=4*wavelength) I have strange curve when the transmitted power is bigger on 60 degrees than on 0 degrees of incidence. Any change of the model size changes curve.
Question: How can changing model size (making it bigger) affect on curve?
