Types Of Antennas Used In Satellite Communication Ppt

Now let us discuss about the satellite antennas.

Types of antennas used in satellite communication ppt.

Used at microwave frequencies when relatively wide beams are required. Antennas are present in both satellite and earth station. Primarily used at vhf and uhf to provide communication with the ttc m system. Satellite antennas four main types of antennas are used on satellites wire antennas monopoles and dipoles.

A variety of antenna types are used in satellite communications. 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. Frequency range 500 1600 khz. For satellite communication frequency ranges from about 0 3 ghz to 30 ghz.

You might be familiar with antennas in general whether or not you understand the working of an antenna. There are two types of horn antenna. The smooth walled conical antenna is the simplest. Antennas in satellite communication types of antenna system use in satellite communication.

The most widely used narrow beam antennas are reflector antennas. 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. Where ever there is wireless communication there is an antenna.

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. Generally consist of paraboloid. M k deshmukh birla institute of technology and science pilani 13 03 2014.

Satellite antennas perform two types of functions. Direction finding of signal propagation. Antennas for satellite communication the antenna is the most visible part of satellite communication system. The shape size and type of antenna might be different but there is an antenna involved none the less.
