CMA Annular ring gap around the feed

Hi! I am trying to simulate a structure which has an annular ring on the patch surface around the probe feed. This gap around the probe is introduced for  matching purpose, I want to see the modal weighting coefficient for the design but issue is that inner probe with this capacitive gap is not coupling to the structure. I have simulated same structure in HFSS and it is giving me proper matching around the required frequency but FEKO can not utilize this gap and zero power from the source is coupled to the structure. I need suggestions

    Hi

     

    Could you attach the model so that we can take a look?

    Its related to my research work and I have to publish it. That is why I can not post it here. I am posting a picture showing top layer of the patch antenna and side view of the structure

    Hi RF

     

    I still can't understand what you are doing. How about some screenshots from your CADFEKO model?
