HORN ANTENNA
Explanation:
A horn antenna or microwave horn is an antenna that consists of a flaring metal wave guide shaped like a horn to direct radio waves in a beam .Horn are widely used as antenna at UHF and microwave frequencies above 300 MHz .
They are used as feed antenna for larger antenna structures such as parabolic antenna as standard calibration antenna to measure the gain of other antenna and as directive antenna for such devices as radar guns, automatic door opener and microwave radiometers.
An advantage of horn antennas is that since they have no resonant element they can operate over a wide range of frequencies a wide bandwidth .
