I want to design Quadrafilar Helical Antenna (QHA). Can anyone support me with references, for calculation formulas and simulation guidance?

I need help to design a compact Quadrafilar Helical Antenna design using 4NEC2 or CST Microwave studio or Ansoft HFSS. Also, It will be great help if one can help me to find out design formulas...
