Re: IE3D Different versions
Hi Jian,
I did not use the geo file of v 9.21, instead I constructed a seperate file for v 11.15. What I tried to simulate was non-radiating edge gap coupled MSA consisting of two elements. One was fed using co-axial probe while other was gap coupled to one of it's non-radiating edge. What I was interested in was the maximum bandiwidth obtained using this configuration. So accordingly I optimized the parameters i.e. gap width and feed point location. what I observed was that both these version gave different values for optimized value of these two parameters. And particularly for maximum bandwidth, using v 9.21 I could only get a bandwidth of 68 MHz, whereas v 11.15 gave me 88 MHz. That is what I wanted to know as to why there is so much differnce between these two values.
Is it only for this particular case of non-radiating edge gap coupled MSA's, as some other papers also have reported disparity between theoretical and measured results.
Sincerely
