A dipole antenna is formed by splitting the
two wires of a two-wire transmission line, and bending them
back to form a single straight line. The antenna feed
is in the middle of the dipole antenna,
where the split occurs. A dipole antenna is
a resonant antenna.
The optimal length of a dipole antenna is one half of the wavelength of the signal
being received or transmitted by the antenna.
A dipole antenna is a narrowband antenna, operating efficiently in only a
narrow band of frequencies.
Dipole antennas are used in in all
frequency bands.
