WebThis is called stub matching. It has two advantages: (a) The length and characteristic impedance of the line remains unchanged. (b) Adjustable susceptance can be added in shunt with the transmission line. Stub matching is of two types: (i) Single stub matching (ii) Double stub matching (i) Single stub matching:-(a) Connection of stub in ... WebThe single-stub tuner requires a variable length of line between the load and the stub, thus it is difficult to make it “adjustable”. The double-stub tuning shown in Fig. 5 uses 2 adjustable shunt stubs in fixed positions. However, the double-stub tuner cannot match all load impedances.
