What Are The Wi-Fi Antenna

Installing a Wi-Fi antenna higher performance is perhaps the simplest and most effective solution to improve the quality of Wi-Fi signal when it is poor. According to its beamwidth three types of Wi-Fi antenna: omni-directional (beamwidth of 360 °, wide open but short range), directional (beam width of between 4 ° and 40 °, narrow beam but far-reaching ) and sector (beam width between 90 ° and 180 °, halfway between directional and omnidirectional).

Improve the quality of the signal with an antenna Wi-Fi

The Wi-Fi wireless connections have become one of the main forms of Internet access in homes, businesses and public spaces for comfort and efficiency.

However, in many cases the quality of Wi-Fi signal is weak, so that one of the topics that most interest among users to improve Wi-Fi coverage.

To improve signal quality Wi-Fi we have several options, but probably the simplest and most effective solution is to install a Wi-Fi antenna for higher performance.

Types of Wi-Fi Antenna

One of the most important parameters of a Wi-Fi antenna beamwidth is, which indicates how open the beam emitted or received by an antenna Wi-Fi to the direction in which maximum power is reached, there being practically radiation outside the beam. Depending on the beam width of three types of Wi-Fi antenna:

Omnidirectional Antenna Wi-Fi: guide the signal in all directions with a large aperture beam (360 °) but short-lived. Usually a omnidirectional antenna for Wi-Fi signal to a nearby area in all directions, for example when you need to give wireless coverage throughout a home, one floor of a building or a park. Wi-Fi Antenna Directional have a beam width between 4 ° and 40 °, so that direct the signal into a narrow beam but far-reaching. Within the beam coverage angle is greater scope, but outside the signal coverage area without power. He often uses a directional antenna Wi-Fi to connect two dots over long distances, for example to provide wireless coverage to a remote PC. Examples of Wi-Fi antenna is directional panel antennas, satellite dishes, antennas, Yagi antennas and screen or grid. Wi-Fi antenna sector, have a beam width between 90 ° and 180 °, which are halfway between the omni-directional antennas and beam width and range. They are typically used when needed to cover a wide area wireless and remote.

Combining several sectorial antennas can get a 360 ° coverage, which is called Wi-Fi antenna array. For this we employ 3 120 ° sector antennas, antennas 4 6 80 ° or 60 ° antennas.
