Parabolic WiFi Booster Antenna - 2.4 GHz

thingiverse

Wifi routers typically come with short omnidirectional antennas. These are vertical sleeve dipoles with 360-degree coverage in the shape of a doughnut. At times it might be useful to have a directional antenna instead, to boost wifi signal strength at a desk, or to access a wifi signal across the street. I created this parabolic reflector that can be slipped onto any router's antenna, to make it a directional antenna. The parabola and the position of the round holder loops of our booster antenna are designed to focus a 2.4 GHz signal on the router's omnidirectional antenna. This wifi booster antenna 1) boosts 2.4GHz Wifi signals from the front, by focussing signal from a larger area, 2) reduces the reception of 5GHz signals, and 3) reduces the reception of 2.4GHz signals from the rear. Essentially it alters the radiation pattern. The router still uses the same power and energy but it is now focussed in a narrow-ish beam. Wifi pentesters and users of AWUS wifi adapters might find this particularly interesting, as it enables handshakes to be captured better from a distance.
