Antenna for wi-fi yourself: a diagram, instruction, description of work

Wireless Wi-Fi technologies are present everywhere. This radio standard provides for the transmission of a signal at a frequency of 2.4 GHz. For practical purposes it is used to switch an interactive connection between the access point and the subscriber's device. The quality of the transmitted signal depends directly on the built-in or external repeater. You can extend the capabilities of the router if you know how the Wi-Fi antenna is made with your own hands. Next, consider several ways and step-by-step instructions to them.

CD Amplifier

To make it quite simply from improvised materials while observing the main rule: the distance from copper elements to the reflective surface of the disk should be strictly 15 millimeters.

The procedure consists of several stages:

1. Take the usual plastic packaging for 25 disks.
2. The fixing protrusion should be cut at a distance of 16-18 mm.
3. With the help of the nail file, spline sockets are made on the plastic spindle to fix the double diamond.
4. The biquadrat (diamond) is made of copper wire with a diameter of 2.5 millimeters.
5. At this stage, you need to be careful, because it is the most important. Take 300 mm of copper cable, protect the surface, bend from a diamond wire. The distance between the centers is strictly within 30 mm. If the whole procedure is carried out correctly, the result is a double geometric figure.
6. Then the ends of the wire are sealed, and the place for fixing the coaxial cable is prepared.

Antenna for Wi-Fi router: assembly and verification

In the next step, it is required to attach the resulting biquad to the spindle, observing a vertical distance of 16 mm at all points. With the aid of a soldering iron the ends of the wire are fixed. Using a silicone adhesive, attach a standard CD-ROM to the bottom of the box. By means of the same adhesive composition, a double diamond is fixed on the spindle.

Then the wi-fi antenna is connected to the router by its own hands. Below is a diagram of how to do this. Experienced craftsmen can decouple the regular antenna and attach a new amplifier, however, one must be very careful here, since thin conductors can become unstuck from the board under the influence of high temperature. An easier way is to install a new device using the SMA connector. The result, despite the simplicity of the process, you will be pleased.

Amplifier from cans

This antenna wi-fi with their own hands is not more difficult to manufacture than the previous version. The device will strengthen the signal, which in the apartment weaken the partitions and furniture. The design in question is simple and cheap.

The following elements are required for the manufacture of the device:

• Wardrobe trempel;
• A pair of liter cans of beer or soft drinks;
• A conventional soldering iron and solder;
• Wire (50 Ohm);
• Connector connector.

Trempel can be replaced with a metal-plastic tube, which is used both indoors and outdoors, as it is not exposed to atmospheric exposure.

Step-by-step instruction

In the future, the antenna amplifier is manufactured in accordance with the following steps:

1. In the bottom of the cans holes are made, after which they are put on the lower part of the trembler or the pipe.
2. The slots in the jars are made in such a way as to avoid excessive tightening or slipping of the part. The pipe is looped and equipped with a suitable retainer.
3. A similar antenna for the wi-fi router located on the trempel requires a cleaning of the soldering site, after which the ends of the wire are soldered to the banks one at a time. The other end of the cable is fixed with the connector used to connect to the access point.
4. If a metal-plastic pipe is used as a base, both banks are soldered to the main wire. Between them, you can equip the adapter and fix the feeder on one of the cans. The antenna screen will be a metal foil, located in the cavity of the tube. In order to solder the braid to the foil, it is necessary to carefully cut and remove the protective film. The fixing point should be fixed and insulated.

Antenna for wi-fi with your own hands from sheet metal

To produce this design, you will need a tin plate measuring 222 by 490 millimeters. It must be bent in the form of a trough. Then, along the perimeter of the core, eight holes are made at the same distance. At the edges they should be 8 * 2 in diameter, and in the middle 8 * 8 mm. These nests will serve as places for vibrators. These elements are easiest to make from tinned food tin, and then solder them in prepared nests.

An amplifier for a tin antenna requires maximum accuracy when observing dimensions. Do not forget to also make holes for the racks. Their diameter depends on the thickness and features of the material used as a holder. On the vibrator side, it is advisable to fill the joints with lacquer or wax to avoid moisture ingress. The connector for connection can be used either (BNC, N, F). The last element is easiest to insulate. With a router, the homemade Wi-Fi antenna is connected by the second end of the wire to the corresponding connector.

Installation Recommendations

When mounting it is desirable to achieve a direct line of sight of the transmitting and receiving amplifier. It should be borne in mind that deciduous trees muffle the signal. The connecting cable must be as short as possible. If this fails, do not use a PCI card.

Typically, it will be sufficient to use a conventional white cable in tight insulation (RG-6U), since the more expensive options have the same effect. If the WI-FI zone is heavily soiled with air and saturation, it is permissible to change the polarization of the amplifier if the connection is made between two identical points. Above, several ways have been considered, how to make a Wi-Fi antenna yourself? Consumer testimonials indicate that such a device has almost the same effect as a factory device, while its cost is an order of magnitude lower.
