Antenna - Bi-Quad W-LAN Wi-Fi 2.4 GHz

I do not know whether it will be interesting. I found the page about a year ago, I wanted to upload it, but the system failed ... the address was lost ... and I forgot about this case. And now stumbled upon.

For a reflector, a piece of foil-wrapped textolite, getinaks or just tin. The dimensions of the reflector are not very critical and, if necessary, can be slightly reduced.

As a double-square holder, a plastic beverage cap is suitable.

Coaxial cable: with a short cable, you can use RG58, but if the cable length is about 2 meters, it is better to take a high-quality cable - Aircell, Ecoflex or similar.

Depending on the quality of the parts used and the accuracy of the assembly, the following depends on whether you get a gain in gain, and therefore a better and more reliable method.

First you need a plastic holder, we take the protective cap from the bike, but the cap from a tube of toothpaste, etc.


We also need a reflector (for convenience of processing, it is better to take foiled glass fiber), a board measuring 10 x 14 cm and a piece of copper wire with a diameter of 2.5 mm2 or 4 mm2

Making a reflector, 10 x 14 cm.The size is not critical and, if necessary, may be slightly reduced.

Cut off the excess.

Find the middle.

Drill a hole a few millimeters in diameter larger than the cable diameter, so that the holder can be fixed with an adhesive gun later.

Cut holder to a height of 18 mm

Use a round file (or something suitable) to make cuts so that the distance between the reflector and the squares is about 15 mm.

Squares can be made from a piece of copper wire with a diameter of 2.5mm2 or 4mm2. It will take about 25 cm.

Squares to bend so that the distance from the middle to the middle of the wire was 30-31 mm. An example of bending wires 2.5mm2.

Continue to bend strictly to fit.

You got these "glasses". Check more
times sizes.

Solder the ends of the wire and zaludite the place of future fixing of the coaxial cable.

Solder the cable.

Glue the holder first, using an adhesive gun.
or some kind of super-glue. Then push the cable with the "glasses".

Now use the glue gun to secure the squares. At
desire to copper parts can be covered with a protective varnish, so that they do not oxidize and
looked good

Fix the cable on the outlet with a glue gun.
