In a pyramidal horn, the dimensions that give an optimum horn are: For a conical horn, the dimensions that give an optimum horn are: where aE is the width of the aperture in the E-field direction aH is the width of the aperture in the H-field direction LE is the slant length of the side in the E-field direction LH is the slant length of the side in the H-field direction. d is the diameter of the cylindrical horn aperture L is the slant length of the cone from the apex. λ is the wavelength An optimum horn does not give maximum gain for a given aperture size; this is achieved by a very long horn.
They are also widely used for terrestrial microwave relay links, ground based and airborne radar antennas, wireless WAN/LAN links, satellite and spacecraft communication antennas, and radio telescopes. History The idea of using parabolic reflectors for radio antennas was taken from optics, where the power of a parabolic mirror to focus light into a beam has been known since classical antiquity. The designs of some specific types of parabolic antenna, such as the Cassegrain and Gregorian, come from similarly named analogous types of reflecting telescope, which were invented by astronomers during the 15th century.
In their astronomical role they differ from optical telescopes in that they operate in the radio frequency portion of the electromagnetic spectrum where they can detect and collect data on radio sources. Radio telescopes are typically large parabolic ("dish") antennas used singly or in an array. Radio observatories are preferentially located far from major centers of population to avoid electromagnetic interference (EMI) from radio, TV, radar, and other EMI emitting devices. This is similar to the locating of optical telescopes to avoid light pollution, with the difference being that radio observatories are often placed in valleys to further shield them from EMI as opposed to clear air mountain tops for optical observatories.
