I am familiar with T lines but not so much with smith chart. so trying to fix that now. I am trying to match a load to the Zo.
After plotting ZL on the smith chart, why is it important to move along the constant SWR circle until it intersects the rotated 1 + jx circle or the 1 + jb circle (assuming ZL is outside the 1+ jx circle)
the actual location of the impedance does not matter in my question - but why move along the SWR circle - to maintain the same reflection coefficient ?
there arent any books or links that intuitively explains this to me about stubs. this is a difference when compared to LC matching networks where we move along constant conductance or resistance circles (since we add only idealized inductors or capacitors to result in a matched condition) - so that explains it for LC - but still confused with stub matching. please explain
if my question is not clear, please let me know.
