Hi, could anyone help me, when we use the suspended microstrip line like above; when the s21 is minumum, what is value (min or max) of current surface density of our EBG? Thanks.
well i am not sure how you model your structure. from your figure it seems you have placed a transmission line at a very large distance away your EBG structure.
how you computte the width of the line ?
i think if you upload your model then people may give you more helpful advice
i have noticed that whenever you model transmission line over EBG structure
CST MWS give warning message saying
waveguide port is inhomogenous. some higher order propagating modes have been neglected please decrease the port size or change the frequency range.
i want to know whether some one else also get these problems or not
it would be great if someone post a simple simulation model of microstrip line over EBG structure which has been simulated without any error or warning messages
