The reflection coefficient describes how much of a wave is reflected by an impedance discontinuity. The reflection coefficient at the load end of the transmission line with characteristic impedance Z0 and load impedance ZL is given by
\(Γ = {Z_L-Z_0 \over Z_L + Z_0}\)
Analysis:
For an open-circuit transmission line, ZL = ∞ (infinite). Hence,
\(Γ = {1-{Z_0 \over Z_L} \over 1 + {Z_0 \over Z_L}} = 1\)
For the reflection coefficient Γ = 1, all of the incident wave is reflected back towards the source.
