Antennas Used In Satellite Communication

Parabolic reflector antenna parabolic reflectors are widely used in satellite communications systems to enhance the gain of antennas.
Antennas used in satellite communication. The shape is generally a paraboloid of revolution. The most widely used narrow beam antennas are reflector antennas. Array fed antennas are often used on communication satellites particularly direct broadcast satellites to create a downlink radiation pattern to cover a particular continent or coverage area. Antennas in satellite communication types of antenna system use in satellite communication.
They are often used with secondary reflector antennas such as the cassegrain. The circular aperture configuration is referred to as a paraboloidal reflector. Reflector antennas are suitable for producing beams which have more signal strength in one particular direction. So parabolic reflectors increase the gain of antennas in satellite communication system.
Hence these are used in telecommunications and broadcasting. Satellite borne communications antennas are located very far from their service area on the earth. The ultimate purpose of the satellite antenna is to act like a spatial filter focusing the antenna beam on the desired area on the earth with the desired polarization while being isolated from other areas. This is the type seen in many home installations for the reception of tv signals.
