Why Do We Use Microwaves For Satellite Communications

This large frequency bandwidth can carry huge information through different band.

Why do we use microwaves for satellite communications. The jers satellite uses wavelengths about 20 cm in length l band this is an image of the amazon river in brazil right. Per martin beckett another reason is that microwave frequencies allow high bandwidth which means high data transmission. The longest frequencies are used in telescopes while the shortest frequencies are used in gps and cellular phones. These satellites make use of different radio and microwave frequencies to transmit and receive data.

Systems which use microwave frequencies are radar mobile radio satellite communications terrestrial line of sight and troposphere links. Microwaves in satellite communication. Microwaves pass straight through the atmosphere and are suitable for communicating with distant geostationary satellites while radio waves are suitable for communicating with sat. Microwaves and radio waves are used to communicate with satellites.

This article concerns the latter and why it is used for satellite communications. Microwave radio transmission is commonly used in point to point communication systems on the surface of the earth in satellite communications and in deep space radio communications other parts of the microwave radio band are used for radars radio navigation systems sensor systems and radio astronomy. An essential property of microwaves is that they travel in straight lines through the atmosphere are not affected by the ionized layers. 3 microwaves can be readily formed into a directional beam which facilitates long distance communication with a minimum of power.

Frequency of microwave bands extends from about one gigahertz to three hundred gigahertz. Why do we use microwaves for satellite communications. Microwaves are used for cooking weather mapping radar and satellite communications as well as cellular phones over the air television signals gps navigation and long range telescopes. To be clear the microwave antenna isn t the only antenna used for satellite communication.

The next higher part of the radio electromagnetic spectrum where the frequencies are.
