inductance from 1/4 to 1/2 wavelength, as a capacitance from 1/2 to 3/4
wavelength, and as an inductance from 3/4 to 1 wavelength, and so forth. A
number of open transmission lines, with their equivalent circuits, are shown
in the illustration.
Impedance of Various Lengths of Shorted Lines
3-131. Refer to figure 3-33 in the following discussion of the shorted line. At
the odd quarter-wavelength points, the voltage is high, the current is low,
and the impedance is high. Because these conditions are similar to those
found in a parallel-resonant circuit, the shorted transmission line acts as a
parallel-resonant circuit at these lengths.
