Spiral Antennas in HFSS

I am designing a one-arm archimidean spiral antenna in HFSS and i was having trouble with calculation of the s-parameters for it. The s-parameter i have measured are completely different from the simlulated ones. I am new at HFSS so im not sure if my design is perfect. Could anyone help me out?

Re: Spiral Antennas in HFSS

If its printed circuit put the thickness to zero if you take thickness ≠ 0 you will get
Big mesh and if you reducing the mesh you will get inaccurate result

also i think that you use infinte ground in hfss model! you should simulate the antenna as you realy implement!

Re: Spiral Antennas in HFSS

Hi....

i had tried hfss v9 to design logarithmic spiral antenna, but when i opened hfss design,
in menu items Draw > Spiral cannot be opened. so i didn't know how to design it again.
can somebody help me to give me steps to design spiral in hfss?
do you have tutorials about design of log-spiral using hfss?

Re: Spiral Antennas in HFSS

hey lanus,
i'm interested in designing a spiral in HFSS too.. can ya pass on the design you have made (the .hfss file), or the reference material you got for making it? did you use the draw equation based curve function in HFSS 10 or did you use scripting??

regards,
wiztronix

Re: Spiral Antennas in HFSS

Hi Lanus….

I tried to design log spiral using hfss, but until now I can’t get the right 2D design because when I finished to create it using line ( it’s still 1D design), 2D didn’t shaped.
Here I send my hfss file, maybe you can help me to find problems and give me the solution for my spiral’s design. O ya about the port, I don’t know in which part of spiral can I put the port? Wave port or lump port? And how?
Sorry if I ask many question because this is the first time for me to use hfss.

thx
