Helix Antenna Design

[Luthiadefit]

I got new project to design helix antenna for 1.6 GHz and 6.6 GHz. I already calculated the parameters needs by an online helix antenna calculator. but my supervisor ask about the equation to get physical construction value.
anyone could help me, please?

The "actual unit" on the turn spacing is unit-less, at least as written for the form. It's in terms of the wavelength chosen. You chose 6.6GHz, so that tells you what the wavelength is... the units you use is up to you (meters, cm, mm, etc.). The turn spacing is some percentage of whatever unit you chose (e.g., if the wavelength was 1 meter, then the turn spacing is 0.31 meter).

S=C/4 (where C is circumference, which is normally chose to be close to one wavelength)

Is this for school? How could you not know what wavelength means? And it looks like your calculator even told you what the wavelength was.

I would look into equations to design a lossless transmission line using the length since your frequency is very high.
