Hi Diane!
Here are the official guidelines to mesh a structure.
From what I see :
I have to say OpenEMS meshing is a pain since it has to be done manually, there are tools out there that can help but never automagically.
The most out of the box solution I can propose you works well with microstrip and lookalikes :
The benefits of going this way are :
The produced script is based on the octave-openems-hll Octave/Matlab library, take a look to check its capabilities.
Hi Thomas, I am a beginner in using OpenEMS and I want to know how to properly use the mesh.x(number) command in OpenEMS. I am writing code to simulate a PCB trace antenna for my internship and I am having problems with some commands. This antenna must work at 2.45GHz for Bluetooth low-energy communication. I change the length of my antenna from 27mm to 30mm to see how the frequency varies. I wrote a message on the OpenEMS forum but I didn't get much response. Only one person replied and told me that my nf2ff dump box is not well defined and therefore my antenna is not centred. This is why I have negative values for gain and efficiency. Here are some images of my result:
Here is the code I am trying to correct. If you have an idea on how I could solve it, I take it:
