Export antenna design to a CAD file

Hi,
I am trying to design an antenna using Antenna Designer app and would like to export the antenna I have designed in a format which can be imported into other software such as CST, sim4life etc?
Conversion to stil file does not seem to be very optimum. Is there a way to export it as a CAD model?
Thanks

Hi Vignesh,
I understand that you are looking for a method to export the antenna design as a CAD model.
You can use stlwrite function to write the antenna design as an STL file. Please feel free to refer to the link below, as it also presents an example for the same.
Currently, MATLAB does not support exporting the design as any other CAD model.

Hi Vighnesh,
I understand the triangulation object error you were facing. I have been able to get the following workaround to resolve the antenna arms separately, such that they can also be written as STL file. Please try the following code.
% Create a vivaldiAntipodal antenna
% Generated by MATLAB(R) 9.13 and Antenna Toolbox 5.3.

%% Antenna Properties
antennaObject = design(vivaldiAntipodal, 1500*1e6);
antennaObject.BoardLength = 0.145;
antennaObject.BoardWidth = 0.05;
antennaObject.Height = 0.00158;
antennaObject.StripLineWidth = 0.00025;
antennaObject.OuterTaperLength = 0.135;
antennaObject.InnerTaperLength = 0.139;
antennaObject.ApertureWidth = 0.015;
antennaObject.GroundPlaneWidth = 0.049;
antennaObject.Substrate.Name = 'Taconic RF-35';
antennaObject.Substrate.EpsilonR = 10;
antennaObject.Substrate.LossTangent = 0.0035;
antennaObject.Substrate.Thickness = 0.00158;
pcb = pcbStack(antennaObject);
top = pcb.Layers{1};
bottom = pcb.Layers{3};
figure,mesh(top,'MaxEdgeLength',2e-3)
[p,t] = exportMesh(top);
tr = triangulation(t(:,1:3),p);
figure,triplot(tr)
stlwrite(tr,'top.stl');
figure,mesh(bottom,'MaxEdgeLength',2e-3)
[p,t] = exportMesh(bottom);
tr = triangulation(t(:,1:3),p);
figure,triplot(tr)
stlwrite(tr,'bottom.stl');
