Building a wireless antenna is not hard. While the underlying physics and

Antennas which are sensitive to the angles of incoming radio waves are called
*directional*. Common uses of directional antennas are at space observatories,
but also satellite TV antennas or military and civilian radars. Directional
antennas come in different forms, a well-known one being the *parabolic*
antenna, which uses a parabolic dish to focus the electromagnetic waves to a
single point.

efficient communication over much greater lengths than omnidirectional or
isotropic antennas. Directional antennas come in different forms, a well-known
