Sometimes the standard radius of the Wi-Fi distribution signal is not enough to make it comfortable to use. Wi-Fi Antenna Made do it yourself, can solve this problem and dramatically increase the communication range and Internet speed.
Materials and tools for homemade:
• textolite;
• vinyl film;
• mounting film.
Wi-Fi Antenna Manufacturing Process
Step 1. Slotting
In the store you need to purchase a vinyl film. We go to any outdoor advertising agency and cut through on film. First you need to get a scheme.
Step 2. Mounting film
You also need to purchase an ordinary mounting film and gently stick it on the vinyl. Carefully peel off from the substrate and stick on one-sided textolite. Then the author removes the film and the circuit remains on the surface of the fiberglass.
Step 3. Immersion of PCB in solution
In the radio store you need to purchase a solution of ferric chloride and dilute it to the color of tea. The mixture must be poured into a tray in which textolite can fit. We load it into the solution for a while and take it out. In those places where there was a film, it must be removed and with a solvent wash all glue from the film.
Step 4. The final stage
A reflector is made and the sides are bent. The SMA connector is cut out, plastic linings are made, the distance between galvanizing and textolite should be 6 mm (it is important to make such a distance). Soldered to the connector and reinforced with hot melt. Through the cable, the design is connected to the router.
Conclusion
A test of such an antenna showed that its radius of action is about 300 meters.
Here is such a small antenna in such a scheme can transmit a signal at a speed of 3 mb / s, and receive at a speed of 5 mb / s.
