"Stub" has more than one meaning and therefore, more than one response.
Your definition of "stub" seems to assume the currents are 180 degrees
out of phase. Therefore, you should not use the word "stub" on a folded
dipole antenna where the currents are in phase.
It's a semantics problem. If you revise your definition of "stub" to
include stubs with in phase currents, you must give up on your present
definition of stubs with only out of phase currents.
Most of us have a feel for the difference between a parallel stub
fed from a line with balanced currents and a series stub where the
currents can have any phase relationship. "Series stubs" is a very
confusing topic and could support a technical article of some kind.
I don't remember it ever being explained in detail before, at least
in the amateur literature.
