Hello to everyone.I have designed a multiband antenna(microstrip rectangular) based on metamaterials(SRR). My resonant frequency is 2.5GHz, but my antenna is also multiband at frequencies 2.6, 5, 7.6, 8.9, 11.8. I have not discrete ports, I have a waveguide port. Can you please explain me from where do derive these frequencies in S-parameters? Why is there a frequency at 7.6 and not at 6 or 8 or anywhere else? My main question is in which theory do the S-parameters based on, so I can realise why I have these results(frequencies).
Thanks in advance
