• Locate x = −j1.16 on the r = 0 circle.
• The stub length (s
1
) required to introduce this suscep-
tance = (0.364 – 0.25)
λ
= 68.4 cm.
• Thus, the stub connected at ‘a’ is 4.2 cm away from the load and its
length is 68.6 cm.
Clockwise rotation
• Rotate in the clockwise direction until the real part of y
in
= 1 (at b) is
reached.
• The distance to move from r
min
to b is also 49.8 cm.
• The location of the stub at ‘b’ is at (54 + 49.8) = 103.8 cm from z
r
.
• At ‘b’, normalised susceptance = j1.16, hence stub must have a sus-
ceptance of +j1.16.
• Locate x = +j1.16 on the r = 0 circle.
• Stub length (s
2
) required to introduce this susceptance = (0.25 + 0.136)
λ
= 231.6 cm.
• Thus, the stub connected at ‘a’ is 103.8 ...
