27 Threads found on edaboard.com: Uwb Antenna Design Using Hfss
my friend and i discussed this problem , and in my opinion : the "solution frequency" is very important to uwb antenna , you know , if it is a frequency fixed MS antenna(has a center frequcny,when you design it ,for example) , the "solution frequency" is just fr, but regarding uwb (...)

I am designing a planar microstrip uwb antenna using a fractal geometry. I am working on hfss. I dont know how to connect the port to my design. Should i use a lump or a wave port. I used a lumped port by creating a rectangular patch between the printed side and additional (...)

It's better that you export your uwb antenna structure in hfss for AWR and import it in AWR. you should select open boundary in AWR and proper grid for workspace. The two simulation results should be close.

I looked into using a ferrite clamp (Fair-Rite 61 material snap-it kit) to suppress leakage current being excited by a uwb dipole. To be honest it didn't really have much effect. Though I do have some data I obtained of Fair rite, which I have attached, and gives material properties up to 3 GHz.
I think using a ferrite bead or (...)
