CPW antenna above AMC

Hi Friends
Recently I have designed a EBG cell which it's reflection phase around 3.5 GHz is zero. In order to use this structure I've used a CPW antenna with resonant frequency of 3.5 GHz. The problem is I expect a resonant frequency of 3.5 GHz for whole structures (maybe with some ripple), but the resonant frequency is shifted to 4.5 GHz and some other resonant frequency is made as well. I've used both transient and frequency domain solver in CST and HFSS and with some reasonable separation between CPW antenna and AMC, but it didn't work. Do anybody had experienced such problem and can help me?
Thanks in advance

I think CST and HFSS can have very accurate results.
Could you upload your CST file?
