Types of antennas used in satellite communication ppt.

Satellite antennas four main types of antennas are used on satellites wire antennas monopoles and dipoles. Wireless communication like infrared communication is an exception. A variety of antenna types are used in satellite communications. M k deshmukh birla institute of technology and science pilani 13 03 2014.

The shape size and type of antenna might be different but there is an antenna involved none the less. Those are receiving of signals which are coming from earth station and transmitting signals to one or more earth stations based on the requirement. Antennas are present in both satellite and earth station. The smooth walled conical antenna is the simplest.

Primarily used at vhf and uhf to provide communication with the ttc m system. The antenna consists of a radiating element that splits the rods and make current flow through the center by using a feeder at the transmitter out that takes from the receiver the different types of dipole antennas used as rf antennas include half wave multiple folded non resonant and so on. A directional type antenna consisting of one or more complete turns of a conductor. Direction finding of signal propagation.

Horn antennas are used directly as radiators aboard satellites to illuminate comparatively large areas of the earth and they are also widely used as primary feeds for reflector type antennas both in transmitting and receiving modes. It determines the direction of arrival of radio signals. There are two types of horn antenna. Now let us discuss about the satellite antennas.

Used at microwave frequencies when relatively wide beams are required. Satellite antennas perform two types of functions. Antennas for satellite communication the antenna is the most visible part of satellite communication system. Where ever there is wireless communication there is an antenna.

For satellite communication frequency ranges from about 0 3 ghz to 30 ghz. Different types of antennas used in satellite communication role of an antenna antenna temperature cassegrain feed antenna parabolic slideshare uses cookies to improve functionality and performance and to provide you with relevant advertising. Antennas in satellite communication types of antenna system use in satellite communication. Generally consist of paraboloid.
