Re: Why the smith loci of microstrip antenna is rotated when
Rotation corresponds to phaseshift, which seems logical to me when you increase feedline length.
But I am a novice on transmission lines, so don't take this for true blindly :)
Thank you for your efford, but your file kept on crashing HFSS (my install seems to be buggy anyway, I got my project corrupted as well, also kept on crashing on that)
Anyway, have been fooling around a bit and documented the steps, for anyone interested, find it attached.
Example is about a...
This one might help:

hilbert curve hfss
I have a periodic frequency selective surface in HFSS, my geometry is as follows:
- vacuum box, where x and y surfaces are master/slave pairs
- bottom boundary set as PEC
- top boundary set as radiation boundary
Inside this vacuum box there is the actual FSS, a dielectric...
Currently working on fractal applications for artificial magnetic groundplanes, which include sierpinski, hilbert and peano curves.
I am really interested in the broadband aspect of fractal antenna's, since, this would broaden the band of my AMC's
I also do this in HFSS (using periodic...
applications of ebg surfaces
This one could be a good starter:
**broken link removed**
Sohn et al investigate 4 types of AMC's for low profile antenna applications: a sievenpiper surface, uniplanar EBG, peano fractal and hilbert fractal curves.
Basically, these all act as a planar resonant LC...
typically, you do not just buy a sheet of it or something, but apply a thin layer of ITO on a glass substrate, maybe you could even purchase a piece of glass substrate with ITO layer on top somewhere, but I couldn't tell you where.
Can't help you with any manufacturer's address I'm affraid
peano hfss
Working on it :)
What exactly are you interested in? I have collected a vast amount of articles during my master research (which I am working on), so maybe I could direct you to something special.
My research focusses mainly on artificial magnetic ground planes for application in...
