How to make an antenna to enhance the strength of wifi signal?

You can use cans that can be seen everywhere in your life to make antennas that enhance the strength of WIFI signals. The specific method is as follows:

1. Clean the used cans and pull out the pull ring.

2. Cut the tank bottom along the red line, and cut off the whole tank bottom.

3. Cut the vest around the red line. At this time, be careful not to cut completely, leave the white line part not to cut, and the white line must be close to the jar mouth.

4. Draw a red line vertically across the blank line, and cut the iron sheet along the red line.

5. Unfold the iron sheet so that the white line of the tank is attached to the base, pass the antenna through the tank mouth, and fix the tank bottom with double-sided adhesive tape.

The signal amplification of cans is mainly because the inner surface of cans reflects radio waves, which enhances the antenna's ability to transmit and receive signals. The router antenna originally emits 360-degree spherical waves. After installing a can, the electromagnetic waves can be concentrated to 180 degrees, which plays a role in making the electromagnetic waves more concentrated, thus strengthening the WiFi wireless signal.
