Hi,
I found out that most of the reflection phase curves shown in IEEE papers on reflectarrays are not experimentally verify and most of the authors only measured their reflectarray radiation patterns but not the reflection phase curve. Why so many researchers don't want to carry out experiment...
Hi,
I saw most of the IEEE papers on reflectarray design had included the value for aperture efficiency.
How can we calculate the aperture efficiency of a reflectarray antenna?
How much percent of aperture efficiency is consider good?
Thanks.
Hi panou,
I have tried floquet boundary with variable size element in HFSS, it were able to generate a phase curve. Then, the phase curve was used to design a small reflectarray in HFSS and it can scan the main beam accurately as we predicted in calculations. Funny, when i import the model to...
For most simple simulation, delta S of 0.01 should be sufficient to get reasonable result since there are only 1% of difference between the outcome of the last two passes.
Some suggestion here, may be you can try slowly reduce the number of pass in HFSS solution setup, since higher pass numbers will need more memory, less number of passes may give results with lesser accuracy but you can roughly know whether your design is working or not. To get most accurate...
some addition information here, when the frequency vary away from the center design frequency, the phase curve will change (become not parallel) and this will lead to gain drop of the reflectarray. So make sure a parallel phase curve at frequency more further than center design frequency will...
Re: simuler un reflectarray avec hfss
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...
yeah, i having the problem too and all free space on my drive are consume when simulate with more numbers of adaptive passes. I found out that the hard disk space (up to gigs size) that used by HFSS fail to restore and now a warning message "low disk space" always displayed when i start my pc...
Hi everybody,
I'm trying to define an E-field monitor in CST simulation to look at the E-field pattern animation. After finished the simulation and when i want to animate the E-field pattern, i saw that we have to choose between several E-field component options like X, Y, Z, Abs and etc, so...
Hi abdoeng,
Do you means define two floquet port at the same time, one port at the top and one port at the bottom of the unit cell? If i have a ground plane, so how many floquet port i have to put?
Thank you
