Single stub matching.
Single-Stub Matching As shown previously, the input impedance (admittance) of a shorted transmission line (a “stub”) is purely reactive. By placing a stub in parallel with another transmission line, the reactive component can be cancelled, leaving a pure-real input impedance. This can be used to achieve a perfect match. Z 0 = 50 Z in = 50 Z L d

The feed line needs to be cut for insertion of series stub. This technique is therefore not commonly used as it is difficult to fabricate in co-axial and striplines. (ii) Double stub matching. In single stub matching, the stub is placed on the line at a specified point.Its location varies with Z R and frequency. This creates some difficulties ...A single stub matching network is chosen to match the two impedances between antenna and the rectifier circuit. A comparison between single, double stub matching network and a circuit without a matching network has been done as shown in Figure-7. It is observed that the lowest input power can be achieved by using single stub matching circuit.
