Hello,
I would like to study on baluns by using COMSOL. I need to convert between a balanced signal and an unbalanced signal. I had assumed that the coaxial lumped port is unbalanced. But after I did some simple test on the Dipole Antenna with a Quarter-Wave Coaxial Balun example, I got confused.
The reason of my confusion is that, There is not a real difference between the electric field distribution on the dipole arms when the balun exists and doesn't exist. I attached both images to this discussion.
Without a balun, Is it supposed to be left arm is not electrified since it is connected to outer metallic shield?
