Loop antenna example
Two loop antennas radiating in air are examined. The lower loop is excitated
by a pulse of short duration.
After the main radiation from the lower antenna the signal propagates
to the upper antenna. There is still much field activity around the lower antenna
for some considerable time as the antenna 'rings'.
