Draw a circle for example in (x,y,z)=(radius,0,0).
Right click choose view and select fit all.
Mark the circle and then select "draw helix" in the top bar menu. This will make a helix with a radius with a center i (x,y,z)=(0,0,0). If this is unappropriate you can define a new coordinate system.
You can choose between dx, dy and dz, this desides in which direction the helix will go.
Kraus' book titled "Antennas for all applications" is a popular and wellknown reference for antenna designers. It should be easy for you to find it in bookstores. In fact, Kraus is the inventor of helix type antenna.
I tried to do,what is needed for drawing a helix but HFSS gives an error such as : Body could not be created for part because of invalid parameters to cREATEhELİX operation.
I will be glad ,if you can say what can I do?

i try to follow your order.. but still i get this error..
Acis error: "Failed to sweep the object."
Body could not be created for part Circle1 because of invalid parameters of this part or some of its parent part/coordinate system
Acis error: "Failed to call api_sweep_with_options.. Acis Error 93009 - The helical sweep results in a self-intersecting body
Body could not be created for part because of invalid parameters to Helix operation.
i don't know but i read other tutorial, but find nothing...
Helix is one of the easiest to construct and has wide bandwidth.coming to your question of what kind of pattern does a helix have. helix is modelled as a loop with 'N' number of elements in an array.
so that pattern of a helix is cos function.i have a Mathcad file to calculate the equations necessary to model a helix, and has the radiation pattern as well. let me know if you would like it.
