Hello,

I need to design an Archimedean spiral antenna in Feko and do not know how to feed that. Can any one elp me about this? Which kind of ports should I use and how?

    You can use the edge port, but if the spiral is imprinted on a dielectric, the edge for the port should either above the dielectric or inside the dielectric.

    Or you could draw a wire across the two arms and use a wire port. The wire should be above the surface if the spiral is printed on a dielectric.

    Try to use FEKO's Component Library Feature to explore more about spiral antennas (wire/planar/cavity backed). You can get more details about the excitation schema of these antennas as well.
