The operating principle of a parabolic antenna is that a point source of radio waves at the focal point in front of a paraboloidal reflector of conductive material will be reflected into a collimated plane wave beam along the axis of the reflector. Diameters commonly range from 4 to 10 feet. K5TRA Paraboloid T.Apel 3 • Plane waves are focused IN-PHASEto the focal point • A paraboloid surface is a parabola rotated about the focal axis • Dish reflectors are usually defined by the intersection of a parapolid and a plane The negative peak of S11 from 5GHz is obtained around -29 dB. • A parabolic antenna is an antenna that uses a parabolic reflector ,or a curved surface with the cross-sectional shape of parabola, to direct the radio waves. The parabolic antenna parameters are: d = diameter of the parabolic dish. But while Once an antenna design is chosen, we design our antenna using a simulation program. Description: Features: Mi-Wave’s 222 & 223 Series cassegrain reflector antennas consists of a parabolic reflector, a primary feed, sub-reflector, and a feed support assembly of four low profile aluminum spars that are attached to the rim if the reflector to position the feed. What is Parabolic Antenna ? Examples of this dish antenna are shown in the following Figures. More modern systems use a steerable parabolic "dish" to create a tight broadcast beam, typically using the same dish as the receiver. The operating principle of a parabolic antenna is that a point source of radio waves at the focal point in front of a paraboloidal reflector of conductive material will be reflected into a collimated plane wave beam along the axis of the reflector. The Parabolic Reflector Antenna (Satellite Dish) The most well-known reflector antenna is the parabolic reflector antenna, commonly known as a satellite dish antenna. The parabolic grids unique light-weight design allows for installation on tower and roof tops that might not be suitable for an equivalent solid antenna. When we first described a parabolic dish antenna, we put a point source at the focus, so This example will analyze the behavior of an equiangular spiral antenna backed by a reflector [1].
