Ah I have the solution now 🥹
It turns out that the distance between the dipoles is too large for the Discrete Port length to be taken into account in the frequency domain solver.
So I ended up having to shrink this distance to less than a certain fraction of a wavelength which was quite...
Just lambda/4, I left everything as default. You can open this Dipole in CST component library, it comes with Transient solver and all the setting is there.
The one with the Time domain sir, which is the default when I open this example. The red TD curve with center frequency is close to 27GHz. But the freq domain solver always gives shallower and drives away from this point.
Hello everyone,
I opened a Dipole originally simulated in Time domain (TD) solver in CST's Component library and found that the Frequency domain (FD) gives completely different results.
This difference persists even though I have tried many different setups i.e. mesh, add more space...
