What type of port to use in FEKO (Quadrifilar Helical)

I have the attached quadrifilar drawn in FEKO. What type of port should I use? In HFSS I put a lumped port at each feed (the bottom 4 traces) and excited them each with the necessary angle. But I'm not sure which port to use in FEKO. Also, let me know if there are any comments on how I have it drawn. The horizontal traces don't line up perfectly with the helicals as can kinda be seen. Thanks.

You can use the edge port on this one. You can also delete the bottom parts and use an infinite ground if you prefer with the edge port.

To fix the CAD, draw the wire helicals and then create a line perpendicular to the helical right at the bottom and use path sweep to give the helicals finite width.

Thank you for your post.

Could you please send me your HFSS quadrifilar antenna file?

I would like to check it out. Thanks.
