Hey Aggraj,
I understand that you have created a custom pixelated microstrip antenna using the Antenna Toolbox in MATLAB and have attempted to mesh the antenna using a maximum edge length (MaxEdgeLength) set as lambda/5, where lambda corresponds to the highest frequency of interest.
However, you encountered an error during meshing for certain structures. MATLAB throws an error message stating that the meshing failed, possibly due to a coarser mesh, and suggests refining the mesh manually.
You want to simulate the same structure with the desired mesh density of lambda/5.
To address this issue, there are a few possible approaches:
- Refine the mesh manually: You can manually refine the mesh in the problematic regions. This can be done by specifying smaller mesh sizes or using mesh refinement techniques provided by the Antenna Toolbox or MATLAB's PDE Toolbox.
- Adjust meshing parameters: Experiment with different meshing parameters, such as the maximum edge length or element size, to find a suitable mesh density that works for all structures.
- Use adaptive meshing: Consider using adaptive meshing techniques that automatically refine the mesh in regions with high gradients or variations. This can help achieve a finer mesh in critical areas while maintaining a coarser mesh in less important regions.
For more information regarding the Antenna Toolbox, you can refer its documentation: Antenna Toolbox Documentation - MathWorks India
Hope this helps!
