Waveguide Horn Antennas
Waveguide Horn Antennas
Horns are open ended Waveguide in which open end is flared so that it looks like horn. Commonly used horn antennas are pyramidal horn, E Sectorial, H Sectorial Horn and the pick up horns. These horns are used to determine the gain of the antenna under test by convectional substitution method and are also used as general purpose radiators. They are also used as reference sources in dual channel antenna test receivers and can be used as pick up horns for radiation monitoring.
