hi ,what kind of reflectarray cell u want?fengzujian said:hi friend!
is there anyone to be farmilar with reflectarray,or did some useful work before,can give me some help about it's simulation.
hi,the main question is how u get the phase figure plot versus cell dimension in IE3Daamir064 said:I dont think that one can use a horn feed in IE3D because it works for planar structures... but me too i am interested in simulating reflectarrays with a horn excitation.. If some one have experiance and a sample project.. please share.
yes,with same results as HFSSHi abdoeng,
Have you try to simulate the reflection phase for a single unit cell with oblique incident wave in CST?
Thanks
floquet mode require periodic structure so we use unit cell in x and y and automaic the port be in top and down the cell unless no E conductor plane at ground
hi ,what kind of reflectarray cell u want?
DRA , microstrip ,aperture coupled,variable slot in ground,rotated elements,proximity coupled,stacked,multilayers
circular polarized,or linear polarized
pls be limited to cerian one as we could help
regards
DRA reflectarray is quite challenge, even you got good simulation result, especially when you come to fabrication of the DRA reflectarray, in practical it is very difficult to position all the DRA blocks accurately like what you designed in simulation and the fabricated DRA reflectarray always end up with DRAs position get shifted by 0.5mm-1mm or rotated by 1 degree-2 degree depends on how good your skill. Since many elements was used, all these small error will add up and give a big different in the experiment results.
