What is a beam antenna?

The

antenna of the beam, also known as Yagi-Luda antenna, Yagi or directional antenna, was invented in 1920 by two Japanese scientists, doctors Yagi and UDA, while experimenting with dipole antennas. Dipole antennas are the simplest forms of antennas and use one piece of wire or single element. TV antennas that are mounted on the roofs are one of the examples of a beam antenna. The central element is called a controlled element and is a place where the antenna is connected to the power line, piece of wire or cable that is connected to the second end to the transmitter, receiver or transceiver. Longer elements are called reflectors because they reflect any signal that passes through the center element. Shorter elements are called directors because they are heading in the direction in which the signal must go.

beam antennas use a technique known as the creation of beam for signal transmission and/or receiving. The production of the beam takes a signal and leads the direction in which it goes. Formation of beams is often used in broadcasting TV and radioEast, amateur (HAM) radio and on mobile phone towers.

Antenna side with smaller elements, directors, is considered the front of the beam antenna, while the side with longer elements, reflectors, is the rear. To get a signal, the antenna is aimed in the direction of the signal and smaller elements pull the signal into the middle element. Longer elements reflect any signal that would be lost back to the center element.

The use of a beam antenna to transmit signal works in the same way. The beam antenna is directed in a direction that the transmitter wants the signal to pass. The signal passes from the transmitter or transceiver, through the glow, to the central element in the antenna. Directors send a signal in the direction of which they have to go, while the reflectors reflect back any signal to be lost towards the smaller elements to be sent.
