Antesky is committed to popularizing various knowledge about antennas and communication industries. What we want to introduce to you in today's article is the origin and development of antennas and introduction to VSAT antenna system.
As we all know, antennas are a very common communication device in our lives. However, most people actually don't know much about it. They may only know that it sends and receives signals.
Since the Russian scientist ( Alexander Stepanovich Popov) successfully invented the antenna in 1894, the antenna has a history of 130 years.
Nowadays, whether it is daily work and life or scientific research and exploration, it is inseparable from the silent dedication of antennas.
So what kind of wire is an antenna, and why does it change our lives so completely?
In fact, the reason why antennas are awesome is because electromagnetic waves are awesome. One of the main reasons why electromagnetic waves are awesome is that they can propagate without relying on any medium. Even in a vacuum, it can come and go with ease and in an instant.
In radio equipment, an antenna is a device used to transmit
and receive radio waves. To put it more simply, an antenna is a
converter converting electromagnetic waves propagating on a transmission line into electromagnetic waves propagating in free space, or vice versa.
There are really too many forms of antennas. Although there are many forms of antennas, they can be roughly classified based on their similarity.
According to wavelength: medium wave antenna, short wave antenna, ultra short wave antenna, microwave antenna
According to performance: high gain antenna, medium gain antenna
According to the direction: omnidirectional antenna, directional antenna, sector antenna
Divided by use: base station antenna, TV antenna, radar antenna, radio antenna
According to structure: line antenna, area antenna
According to system type: unit antenna, antenna array
We are showing the details about parabolic antennas, please click this article about parabolic antenna type.
If divided according to appearance, the common ones are as follows:
whip antenna
Yagi antenna
Examples of parabolic antennas.
