Single-stub matching is a very common method for impedance matching using microstrip lines at frequences in the UHF band (300-3000 MHz) and above. In Figure 3.23.1 , the top (visible) traces comprise one conductor, whereas the ground plane (underneath, so not visible) comprises the other conductor.The single stub matching technique is quite popular in matching fixed impedances at microwave frequencies. Arpan Deyasi Electromagnetic Theory 38. 24-11-2021 Arpan Deyasi, EM Theory 38 Impedance Matching on Transmission Line: Single stub matching ZL Z0 l1 l2 Arpan Deyasi Electromagnetic TheorySteps to Solve a Single-Stub Matching Problem Goal: Design a single-stub matching network such that Y IN = Y STUB + Y A = Y 0 1) Convert the load to a normalized admittance: y L=g+jb 2) Transform y L along constant Γ towards generator until y A = 1 + jb A – This matches the network’s conductance to that of the transmission line and determines dThe single stub matching is popular in matching fixed impedances at microwave frequencies. Parallel Stub: Series Stub. But it is not suitable for matching variable impedances. A change in load impedance results in a change in the length as well as the location of the stub, so every load needs a new stub position.That is, any structure which employs a quarter-wave match will be at least \(\lambda/4\) long, and \(\lambda/4\) is typically large compared to the associated electronics. Other transmission line matching techniques – and in particular, single stub matching (Section 3.23) – typically result in structures which are significantly smaller.
