hfss equation surface cover lines
try my simulation
that's totally working
and i designed it on hfss v10 as you tried.
spiral command works for any 1 or 2 dimension object and it makes that object a spiral. you need an object to make a spiral using spiral command.
and it makes archimedean spiral i had to design equiangular spiral so i used draw>equation based curve and used parameters for it. hope it helps.
I would like to know how to read a file .rar under hfss
rar is an archive. Use Winrar to open and extract...
help me......
in my log-spiral antenna design, Z parameter has large real and imaginer, for real about 220 ohm and for imaginer about 200 ohm. but in theory, there isn't imaginer in spiral and real is only about 188.5 ohm.
How to reduce that imaginer and decrease that real?
thx..
hi...
do you use low-order with lambda ref. in the simulation?
what do you mean about low-order with lambda ref?
do you know how to create balun or matching impedance
for my log-spiral antenna? i have an antenna with approximately 220 + j200 ohm, in frequency range 1.8 - 6 GHz.
in hfss design, i put lump port in center of spiral, between 2 spiral arms.
i want to match it with coaxial 50 ohm.i don't know too how to create
balun or matching impedance in hfss
must i change the port become wave port?because i only use planar log spiral.
do you have equations for
4-arms log-spiral antenna or more than 2-arms
log-spiral antenna? because i must simulate and analyze that for
the addition for my final project.
thank you for helping me...
regards
hi all
any one know that how we could feed a four arms spiral antenna ?
Spiral antenna simulation is a fascinating topic! I get good results for an equiangular spiral antenna at 10 GHz! Good circular polarization. The simulation did not seem to take as long as often feared: 3hours!

How to use matlab to plot then send to HFSS?Thank you for your answers.
it is impossible, you could generate the spiral points and then use these points information in HFSS or in HFSS 10 you could draw by equation
please help me
does somebody have Archimedean spiral antenna examples? I use hfss10.
Thanks
one of the arm is suppose to be gnd while one of the arm is the conducting arm right?
from your picture, did you draw the line from the ground to the conducting arm?
i have did it but it cant work
I see a spiral feed as a "differential" port, therefore there is no gnd, as would be normally for i.e. microstrip (that is trace and groundplane). Lumped port does the job very well. The integration line is from one spiral to the other, simple as that. Isn't this obvious from the pictures?
