Default hi sos

hi every body

i want modelize a qudrafilar helix antenna utilizing ANSOFT Designer
SV or with matlab but i dont know how create the geometry of the
antenna

if someone can help me to do it i'll be thankful

thank you at advance

Hi "disc"

I can model a Quadrafilar helix antenna with EZNEC. Roy has made it easy
to model helix antennas.
I can also offer you an antenna design concept that performs better than a
Quad Helix for an antenna located on Earth and expected to have a
hemispheric coverage with Circular Polarization. Google DCA APT antenna
for satellite reception.

Hi "disc"

I can help you a little with learning to use EZNEC to model a Quad Helix.
I have a few Quad Helix antennas modeled for 137 MHz. That data is
available to you.
I can show you how to design your own hemispheric coverage antenna that
will perform better than a Quad Helix for reception of signals from polar
orbiting satallites.

What do you want to do?
