A monopole antenna is a resonant antenna that can
be thought of as being one arm of a dipole
antenna, with the other arm having been removed.
The optimal length
of a monopole antenna is one quarter of the
wavelength of the signal being received or transmitted by the
antenna.
A monopole antenna is a narrowband antenna, operating efficiently
in only a narrow band of frequencies.
Monopole antennas are used
in in all frequency bands.
