What is the omnidirectional Wi-Fi® antenna?
The
omnidicerous Wi-Fi® antenna is a vertical antenna that usually emits its signal in most directions. The signal strength decreases with distance and is often weaker directly above and below the antenna; Longer vertical often provides better performance. Omnidiviceal antenna can also receive signals from all directions. Many wireless routers and Wi-Fi® access points uses the Wi-Fi® oscillation antenna to achieve all rooms in the house or office. Some proposals have a greater profit - signal amplification and receiving sensitivity - than others. One of the smallest profits is commonly used on most wireless access points and routers. Often known as a "rubber duck" is named for a flexible rubber cloak, which makes the Wi-Fi® antenna more resistant. It is basically a piece of coaxial cable with a simple metal department separating the shielded and unshieloded part of the cable. Compared to the perfect isotropic antenna, this design has a typical profit of 2-2.2 decibels (DBI).
Omnidiceontal Wi-Fi® antenna with better gain is a long piece of copper wire with several carefully created loops; A profit of 4-15 dBI can often be created depending on the length and number of loops used. The wire is often closed in some form of plastic tubes to maintain its critical shape. Whip antennas mounted on vehikulus are variations in this design. The Wi-Fi® omnidicer antenna with about 6-8 dBI profit can also be made of eight very carefully designed coaxial cable segments. If the space is very limited, an alternative with a lower profit is a quarterly "spider" antenna-rating (RF) connector with a metal base, a little coaxial and four stiff wires of the "foot" to form a ground plane.
A Wi-Fi® antenna Wi-Fi can be used in a home or office environment. Unlike the Wi-Fi oscillation antenna, the transmitted signal focuses in only one direction; It also receives signals mainly from the same direction. ProfitThe antennas are often much higher than ubiquitous, by 15-24 dBI or more. The signal is usually concentrated by a metal cylinder, bowl, net or other reflective surface; This is also ideal for communication with long distance point-to-point. Both types of Wi-Fi® antennas can be used together-in-directional, which serves small areas, combined with a remote network connection.
It is possible to build an antenna Wi-Fi® or buy one finished Manup. Many books and websites illustrate how to build different types of Wi-Fi® antennas. They can often be designed using simple tools and cheap materials. Some creative people even built the directional antennas of cans and cooking WOKS. A large number of commercial retailers also sell mass-produced Wi-Fi® antennas.
