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.
