Yes and, being open-ended, is a *standing-wave* antenna.
Contrary to what has been said here on r.r.a.a in the
past, Balanis says: "The current and voltage distributions
on open-ended antennas are similar to the standing wave
patterns on open-ended transmission lines. ... Standing
wave antennas, such as the dipole, can be analyzed as
traveling wave antennas with waves propagating in opposite
directions (forward and backward) and represented by
traveling wave currents If and Ib in Figure 10.1(a)."

Why would that be of any advantage? Do you believe it is easier to solve
for the exact radiated fields by partitioning the standing wave into
two components?

The real challenge in antenna theory is determining the exact current
distribution. Further subdividing or superposing the current is a
trivial exercise in comparison, and such manipulation may or may not be
useful.

In other words, what Balanis says may be true, but so what?
