Spiral Antenna Related from Antenna Tool box

Hi Ones we create a spirl antenna using equiangular spiral antenna code how do we extract x and y coordinates from the plot for preparing a art work (or for exporting into DXF Autocad)?

This can be done but requires a little bit of work.

In 15b Antenna Toolbox (ver 1.1), there is a method called exportMesh which will give you the points and triangles used to solve the structure. [p, t] = exportMesh(antennaObj);

You can pass the p and t matrix to triangulation class in MATLAB

TR = triangulation(t(:,1:3), p);

The triangulation class has a method called freeBoundary which will give you the border edges of the spiral.

FF = freeBoundary(TR);

The border edges along with the point set p, will give you the outer boundary of the spiral for art work.

I hope this helps.
