Hello all,
I have one problem with designing log-spriral antenna. I used CST MWS 2012. I created analytical curve with these parameter:
Code:
' bodySub Main ()'@ define curve analytical: curve1:ramenoWith AnalyticalCurve .Reset .Name "rameno" .Curve "curve1" .LawX "0.5*diameter_inner*Exp(Ln(diameter_outer/diameter_inner)*t/(2*pi*num_turns))*Cos(t)" .LawY "0.5*diameter_inner*Exp(Ln(diameter_outer/diameter_inner)*t/(2*pi*num_turns))*Sin(t)" .LawZ "0" .ParameterRange "0", "2*pi*num_turns" .CreateEnd WithEnd Sub
Do you have some idea? How to increase the number of points?
Thank you for answer

When I did my Terahertz spiral antenna design in ADS, I created all the points in a Excel spreadsheet, then I imported those points as the X-Y coordinates to draw a custom line. I am sure you can do the same in CST.
I did a logarithmic Spiral using this equation
See attached Excel spreadsheet.
It was about 10 years ago.
