Hi,
As per my understanding you want to mount the antenna array on to a large metallic cylinder.
You can make a cylindrical cavity and store it as an STL file using the following code:
h = cavityCircular( 'Radius', 1, 'Height', 0.5);
z = impedance(h, 1e8);
stlwrite(h, 'rectcavity.stl');
For more info on the cylindrical cavity, please refer to the documentation https://in.mathworks.com/help/antenna/ref/cavitycircular.html
After creating the structures on which we have to mount our antennas, we create a base from the above structure.
base = platform('FileName', 'rectcavity.stl', 'Units', 'm');
show(base);
The user defined platform can be specified in the installed antenna analysis, and you can choose the antenna element and its location on the above platform and do the required analysis.
Please refer to the following documentation for more info on the installed antenna analysis.
I hope it helps!
Thanks.
