How to add a 50-ohm resistor on the gap of a patch structure ?
I built a patch structure with a gap on its edge, where I wanted to load a 50-ohm resistor. I have tried to build an edge port or wire port across the gap and used the "add load" function. But the error appeared when I run it. And I hope someone will tell me the right way to build and mesh it.

A model with a dielectric cannot be fed directly on the surface of the dielectric. Meaning the edge for the edge port cannot be exactly on the surface. But it is allowed to place the edge above or inside the dielectric.
In the below, I modified the feeding strip to be elevated above the dielectric.
As stated, you can also place it inside the dielectric:
The height of the edge above or below the surface should be similar to a triangle edge length.
In the above I also added some local meshing on the edges of the "U".
If it is absolutely critical to feed exactly on the surface, a FEM solution would need to be created.

Thank you for your answer. I also tried this folded structure before reading your answer, but I don't know the principle. I got a lot out of your answer.
