Image smith communications5/26/2023 Therefore, from the fig., gamma can be expressed as, The amount of reflected wave depends upon the mismatching of the source and load impedances. The ratio of the voltage of reflected wave and the voltage of incident wave is known as the reflection coefficient. If there is impedance mismatching, part of the energy in the incident wave is reflected back giving rise to a standing wave. transmitter to antenna or antenna to receiver), the impedance of source must be equal to the impedance of load. While transferring the RF waves on a finite transmission line, for maximum power transfer from source to load (i.e. These are the impedance matching circuits. Transmission lines are the circuits that deliver power from a transmitter to an antenna and from an antenna to a receiver.
