Antenna coarsen mesh on outer contour, parameters

Hi,
I am using the Antenna Toolbox to create a PCB-Patch Antenna, i have a few Problems with the mesh:
Please look at the picture below, it shows one of the 4 edges (dielectric) of my rectangular PCB-Patchantenna, the top metal layer is only in the middle and does not reach the rim, the GND layer shape is the same as the dielectric. The Feed sits in the middle. My problem is that the mesh always gets very fine at the outer contours of the board (although a coarse mesh would be totally sufficient), and i am doing antena optimization so i really need to minimize the computation speed. How can I get the mesh(...) - function to coarsen the mesh on the outside but leave it fine as it is on the inside?
Thank you very much!

Hi,
As per my understanding, you want to customize mesh.
You can set mesh mode to manual. You can also adjust the MaxEdgeLength and MinEdgeLength to customize mesh.
For more information go through the following links

Hi apex,
p=patchMicrostrip('Substrate',dielectric('Fr4'));
pcb=pcbStack(p);
mesh(pcb,'MaxEdgeLength',0.1);
In tha above figure mesh is coarse at the outer edge.we can give you a better solution if you can share us the reproduction steps.
