I am working on characteristic modes theory of antennas using Feko 7.0 and I have simulated one rectangular patch and found that eigenvalues, modal significances with respect to frequency are not properly tracked. So can you please tell me how the mode tracking options are activated in Feko7.0 or is there any tab or dialogue boxes in simulator window so that I can manage to introduce mode tracking in simulation results?
I have learnt later that FEKO has its inbuilt mode tracking systems. What you have to do is to use "discrete point " settings when select frequency range because modal correlation/ tracking cannot be calculated in continuous frequency range settings..
