Module 6.6 Double-Stub Impedance Matching (one-eighth wavelength)

  \(Z_{o}\) (characteristic impedance) : 50 \(\Omega\)
  \(Z_{L}\) (Load impedance) :
+ j \(\Omega\)

Z Chart ZY Chart

The normalized input admittance ( \(y_{in}\) ) at the point P looking toward the load :

\(y_{in}\) = + j

Task: Follow the steps below to design a double-stub matching network between the load impedance \(Z_{L}\) and source impedance \(Z_{o}\).
(Move the input impedance at the observation point P to the center of Smith chart.)

Show \(y_{L}\) (normalized load admittance)=+ j

Add a transmission line of length d=1/8λ
