This is where the Smith chart can be useful. One approach to impedance matching is to use shorted transmission-line stubs in parallel with the transmission line. Figure 5 shows an example.

chances are good that coax stubs seem a bit baffling to you. They look for all the world like short circuits or open circuits, and yet work their magic and act to match feedline impedances or even ...
