Various uses of the dipole antenna

How a dipole antenna actually works and what are its main functions are basic things that someone needs to know, whatever their technical abilities. It is not actually rocket science as many people have had it at one specific point in their past and they are quite familiar with its look. You may know this type of antenna, because is one of the most known. It is used alone or with other types of antennas to reach for more frequencies. It is quite easy to build and even easier to use. The whole calculation process is quite interesting and easy, but if someone goes into deeper uses, things can get really complicated.

As the name of it says, it has two poles, that let the radio frequency flow through them easily. In this process the radio signal is amplified by the current voltage. In that way the antenna will be able to freely connect to a feeder. When it comes to the basic antenna it is clear that the current will be distributed in a sinusoidal manner. This means that each cycle will have a maximum and a minimum reach. That for current flow, while the voltage pattern is different. It will have a low middle and then at the very end it will go to its maximum. So at the center of the process one will be at its highest point, while the other at its lowest.

The different uses of dipole antennas are multiple; from military uses to civil uses. The use for TV's is most known for many of us. If you never seen one (check the picture), it is distinguished by its two opposite loops. This is used to get TV signal and the length of the ears can be adjusted at the right angle and also the proper length. Another type of antenna is the folded dipole. It is usually used for the FM band. Both dipoles meet each other in the feed point section. It receives best the one wavelengths. They are not sophisticated but they work out perfectly.

Another type of dipole antenna is the one named whip. It is actually a monopole and it covers only half of a normal dipole one. The dipoles are considered to be more efficient than the whips. Advantages of monopole antennas are they need less space. The use of towers is common when it comes to dipole antennas. The Waesaw tower is one such example, and it functions on long wave signals. The military use more than one on their towers. For special

frequencies they use multiple antennas. As it is with any other technology, there are improvements that are made even to this simple one.
