Open Circuited Transmission Line - DE Notes

The minimum current flow takes place at open circuited end. At λ/2 away from the open end of the transmission towards the source, the behavior at this point will be capacitive. This behavior will repeat 5λ/8 from the open circuit end. At λ/4 of open circuit end of the transmission line, the circuit will behave as a series resonant circuit.
