Directional double BiQuad WiFi antenna 2.4GHz

thingiverse

If you find yourself facing a garage or other space where WiFi reception is weak due to being too far away from your access point or modem, this directional BiQuad WiFi antenna might be just what you need. With this antenna, you can significantly boost the working distance of your WiFi by up to hundreds of meters. All you require are: Copper electrical wire (1.5mm squared or 1.33 diameter in millimeters) An antenna base connector (I used a BNC here, but "N" is better) Some metal reflector where you can solder on My 3D printed mold. The costs of this project are only a few dollars or Euros. This antenna also works great with the WiFi Pineapple Tetra or Nano. Check out the video for the build of this antenna: https://youtu.be/DToyFX81tm0 Print Settings: Printer: Da Vinci Pro Rafts: No Supports: No Resolution: 0.2 Infill: 15% Post-Printing: How you make it Start by straightening the copper wire and creating a 90-degree angle. Now bend the wire in the mold using pliers, ensuring the wire never touches itself by insulating the pieces where it touches. Watch the video to see how to bend the wire in the printed mold. You can leave the wire in because you use the mold to keep the antenna at the correct distance. Use a metal (copper or tin) plate of about 25x18cm in size. In the middle of the plate, drill a hole the same size as the connector you are using. Place the connector in this hole and secure it. Now place the antenna on the connector and solder the two wires coming from it to the ground of the connector and the metal plate. Solder the live end to the part of the antenna I point out in the video. Now, you have a perfect WiFi antenna to use with a WiFi card or USB WiFi dongle that has an antenna connector. How I Designed This 123D Design The antenna was drawn in 123Ddesign to ensure I had all the correct measurements, and because the cable is inserted into the printed mold, you can't make a mistake with the length of the copper wire. The frequency where the antenna is 1:1 is at channel 6 of the WiFi spectrum.
