b. The open-circuited, quarter-wave line acts like
a
series-tuned
circuit. It presents a low impedance to the generator.
c. The quarter-wave line inverts the load, that is, a short circuit
looks like an open circuit to the generator, while an open circuit appears
as a short circuit.
d. The voltage and current are shifted
90
degrees
because of
the
inverting properties of the quarter-wave line.
e. Common applications of the quarter-wave section of transmission line
are described and illustrated in Figure 20.

from main transmission line enters
the quarter-wave
section.
(b) Standing waves of E and I are set up.
