hi, my question is in regard of a printed (microstrip) dipole antenna. I know that a balun acts as an unbalanced to balanced line transformer. (in my case of the dipole antenna: the coaxial feed is unbalanced and the half-wave diple antenna is balanced, so i need a balun.) But what exactly does "unbalanced" and "balanced" mean in this case? Im a bit confused as on many sites the balun seems to be seen as an imedance transformer (like a quarter wavelength transformer) only. So how exactly does it work and what exactly is it needed for in my case? Im happy about every answer that sheds some light into my dipole-darkness! :D thank you!
