1. As 30 cm = 0.1
λ
, move clockwise (i.e. towards the generator)
along the circle from z
r
by 0.1
λ
and mark this end point as A.
The value at A is the input impedance z
i
(=0.24 + j0.481).
2. As 90 cm = 0.3
λ
, move clockwise (i.e. towards the generator)
along the circle from z
r
by 0.3
λ
and mark this end point as B.
The value at B is the input impedance z
i
(=0.83 + j1.63).
3. As 120 cm = 0.4
λ
, move clockwise (i.e. towards the generator)
along the circle from z
r
by 0.4
λ
and mark this end point as C.
The value at C is the input impedance z
i
(=0.39 – j0.93).
These steps are shown in Figure 6.36.
