Information on Paraboloid

The dimensions of the radiating surfaces of many Paraboloids are large compared to the wavelength used and they behave in a similar way as reflecting mirrors do at optical frequencies. Hence, geometrical optics, which is based on rays and wavefronts, may be used to study certain aspects of these antennas. A Paraboloid surface has the useful property of being able to convert a diverging spherical wavefront into a parallel plane wavefront, thereby producing a highly focussed or narrow pencil beam. This property of focussing that is usually associated with light rays, mirrors and lenses, can equally be applied to parabolic reflectors at microwave frequencies.
     The Paraboloid is most commonly used as a UHF antenna or SHF antenna.
