I have been trying to find the far field radiation pattern of a monopole antenna placed inside a photonic crystal using MWS. Transmission and S11 simulation results match the experimental results. But somehow far field radiation pattern isn't even close to experimental data. I ve run the simulation multiple times with many possible settings. Still no sensible result. I ve suspected that the reason for inconsistency is related to the high Q value near the band edge frequency. Since the group velocity near the band edge is very low these frequencies decay very slowly. Would it be better to use HFSS for this structure? I would appreciate your suggestions. I may add good results to a publication if I can get some. I have attached the structure (.mod file and the .sat file are included in the .rar file).
