Helix Antenna Design

RE: Helix Antenna Design

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)

RE: Helix Antenna Design

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