quadrifilar helix antenna

hello

i m designing quadrifilar helix antenna in hfss for 400 MHz... so pls give me some solution for modelling the structure of quadrifilar helix ... if u have any info regarding ths thn pls share this to me at chaitu.8788@gmail.com


thnking u in advance

Have you looked into this paper.

i was designing my own Quadrifilar helical antenna on hfss,but i stopped because of other endeavors.i can provide you the half done quad helix if interested. well the remaining part is the actual challenge in the design.but anyway let me know

Download the Antenna Design Toolkit from ANSYS. It is an unlicensed product that will create ~40 or so antennas including several variations of quadrifiliar antennas :)

Have Fun

hi

if u can send me that file thn pls do it and thnx in advance for that..

Here's another file of Quadrifilar helix at 400MHz.

Hope it helps

hello

i am on way to designing QHA for 2,4GHz antenna. i am using CST 2011..
i would like to ask you how to make design for this antenna.
i had made a monofilar antenna for 2,4 GHz. then feel little bit confuse about changing the pitch angle. and diameter between small loop and large loop
if you like, can you tell me what kind of parameter that i can use to change them.
at least what can i do in "analytical curve" at CST's option..
thank you very much
:D
