Answer:
The load reflection coefficient,
Reflection coefficient at input,
SWR = 4.26
Given:
Characteristic impedance of the co-axial cable,
Length of the cable, L = 2.0 cm = 0.02 m
Dielectric constant, K = 2.56
frequency, f = 3.0 GHz =
Explanation:
In order to calculate the reflection coefficient at load, we first calculate these:
The line input impedance is given by:
(1)
Now, we calculate the value of :
(since, )
Now, Substituting the value in eqn (1):
Now, the load reflection coefficient is given by:
Thus
Similarly,
Reflection coefficient at input:
Now, the SWR is given by:
SWR, Standing Wave Ratio =
SWR =
