When a transmission line is terminated by an impedance Z, then reflection coefficient are:
Here, Z0 = Characteristic impedance of transmission line.
Since Z = Z0 therefore reflection co-efficient of voltage (pv) and current (pI) both will be zero, i.e there will be no reflection of incident wave.

Transmission Line Termination by Characteristic Impedance
A transmission line is a type of cable used to transmit electrical signals from one point to another. It consists of two conductors separated by a dielectric material. The characteristic impedance of a transmission line is the ratio of the voltage to the current in the line.
When a transmission line is terminated by its characteristic impedance, several things happen:
No Reflection of the Incident Wave
The most important thing that happens is that there is no reflection of the incident wave. This is because the termination impedance matches the characteristic impedance of the line, so there is no mismatch between the two. As a result, all of the energy in the incident wave is absorbed by the termination impedance, and there is no reflection.
No Incident Current
Another consequence of terminating a transmission line with its characteristic impedance is that the incident current is zero. This is because the termination impedance is equal to the characteristic impedance of the line, so there is no voltage drop across the termination. As a result, there is no current flowing into the termination.
No Maximum or Minimum on the Line
When a transmission line is terminated by its characteristic impedance, there are no maximum or minimum points on the line. This is because there is no reflection, so there are no standing waves on the line. As a result, the voltage and current are uniform along the entire length of the line.
Conclusion
In conclusion, when a transmission line is terminated by its characteristic impedance, there is no reflection of the incident wave, no incident current, and no maximum or minimum points on the line. This is why terminating a transmission line with its characteristic impedance is so important in electrical engineering.
