Feed Horn – Definition and Pronunciation
What is Feed Horn?
Feed horn is a device that in a transmitting system directs the signals onto the reflector surface for focusing into a narrow beam aimed at the satellite, and/or in a receiving system collects signals reflected from the surface of the antenna. In a receiving system it collects microwave signals reflected from the surface of the antenna. In a transmitting system it directs microwave signals onto the reflector surface for focusing into a narrow beam aimed at the satellite. The feed is designed to match a particular antenna’s geometry (F/D ratio) and is mounted at the focus of the parabolic reflector.
Examples of Feed Horn
The antenna used in this application is a low profile waveguide horn array. The Mantarry M40 is a mechanically steered waveguide horn array antenna. The M40 designation reflects the number of feed horns across the width of the aperture.
From “Aeronautical Mobility Services”.
A basic HTS approach is to use a specified number of feed horns in space (say 24) fitted on a geometric matrix and illuminating a single reflector (a spacecraft may, in fact, have multiple such arrangements of feeds and reflectors, say three or four or more).
From “High Throughput Satellites (HTS) and KA/KU Spot Beam Technologies”.
