A loop antenna consists of a loop of wire,
with each end of the loop connected to one conductor
of the antenna feeder.
The most common application for a loop
antenna is direction finding. The purpose of direction finding
is to identify the direction from which radiation arrives at
a receiver. Direction finding is an important part of aircraft
and ship navigation systems and electronic warfare.
A loop antenna
is commly used as the antenna for an aircraft's automatic
direction finder (ADF). In this application, the insensitivity to the
elevation angle of the received radiation is of benefit.
