Antenna Designing using MATLAB antenna toolbox

Hello sir, I'm unable to add a cylindrical dielectric layer using matlab antenna toolbox. Please help me, if its possible to add cylindrical dielectric layer using antenna toolbox?

Hi,

As of now, there are no 3D shapes yet to create the 3D shapes for the dielectric. Instead, the 2D shape can be passed to the BoardShape property of pcbStack and BoardThickness can be set to create the cylindrical dielectric layer.

The following code may provide you a better understanding.

p = pcbStack;

p.BoardShape = antenna.Circle('Radius',1e-3);

p.BoardThickness = 1e-3;

d = dielectric('Teflon');

d.Thickness = 1e-3;

patch = antenna.Rectangle('Length',0.5e-3,'Width',0.5e-3);

gnd = antenna.Circle('Radius',1e-3);

p.Layers = {patch,d,gnd};

p.FeedLocations = [0,0,1,3];

p.FeedDiameter = 0.1e-3;

figure; show(p);
