Satellite Communication Antenna Definition

A parabolic antenna is an antenna that uses a parabolic reflector a curved surface with the cross sectional shape of a parabola to direct the radio waves.

Satellite communication antenna definition.

Satellite antenna synonyms satellite antenna pronunciation satellite antenna translation english dictionary definition of satellite antenna. Those are receiving of signals which are coming from earth station and transmitting signals to one or more earth stations based on the requirement. Satellite antennas perform two types of functions. Commonly known as community antenna television catv these cable systems use a community antenna to receive broadcast signals often from communications satellites which they then retransmit via cables to homes and establishments in the local area subscribing to the service.

High amount of data can be transmitted with the help of satellites. An antenna is a transducer that converts radio frequency rf fields into alternating current or vice versa. Subscribers pay a specified monthly service charge in read more. The horn antenna is an example of an aperture antenna that provides a smooth transition from a waveguide to a larger aperture that couples more effectively into space.

The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish. The different types of antennas used in satellite communication are as follows. In other words the satellite antennas receive uplink signals and transmit downlink signals. The main advantage of a parabolic antenna is that it has high directivity.

It functions similarly to a searchlight or flashlight reflector to direct the radio waves in a narrow beam or receive radio waves from one particular direction only. The antenna transmits and receives the modulated carrier signal at the radio frequency rf portion of the electromagnetic spectrum. There are both receiving and transmission antennas for sending or receiving radio transmissions. Antennas for satellite communications the antenna is the most visible part of the satellite communicationon system.

Antennas play an important role in the operation of all radio equipment. Satellite communications also provide weather information. Communication satellite comprises of a transponder antenna communication payload switching systems command and control system. We know that the length of satellite antennas is inversely proportional to the operating frequency.

Parabolic reflector antenna with offset feed. N an artificial satellite used to relay radio television and telephone signals around the earth usually in geostationary orbit collins english dictionary. A dish antenna also known simply as a dish is common in microwave systems.
