How to get the coordinates of a Koch snowflake fractal antenna designed using the Antenna Toolbox?

I am trying to the coordinates of a Koch snowflake fractal antenna designed using the Antenna Toolbox.

Ail I get is a picture, and the antenna performance.

I would like to have the coordinates so I can modify the design and/or send to fabrication.

Thank you

Hi @Pierre,

The coordinates of the antenna can be found using the “mesh” command.

Here is a sample implementation-

% create a Koch snowflake fractal antenna with specified iterations
antenna = fractalKoch('NumIterations', 3);

% display the antenna structure
figure;
show(antenna);
title('Koch Snowflake Fractal Antenna');

% perform an analysis to generate the mesh
freq = 1e9; % Example frequency for analysis (1 GHz)
impedance(antenna, freq);

% extract the mesh data of the antenna
meshData = mesh(antenna);

% get the vertices (coordinates) from the mesh data
vertices = meshData.Points';

% export the vertices to a CSV file for fabrication or further modification
csvwrite('antenna_vertices.csv', vertices);

% display the coordinates of the vertices
disp('Coordinates of the antenna vertices:');
disp(vertices);

% visualize the extracted vertices
figure;
scatter3(vertices(:,1), vertices(:,2), vertices(:,3), 'filled');
xlabel('X-axis');
ylabel('Y-axis');
zlabel('Z-axis');
title('Vertices of Koch Snowflake Fractal Antenna');
axis equal;

The above code will give you the following figure:

You may refer to the following documentation for more information on “mesh”.

Hope this helps!
