Building a Cantenna from a Pringles can « Antenna Magus blog. Cantenna made from a Pringles potato chip can. A couple of months ago I blogged about how hard it is to find reliable measured data for a Cantenna (also known as the Pin- fed circular waveguide antenna) which we wanted to use to verify our Antenna Magus design. You can read the blog here. We decided to make and measure one ourselves. After designing a Cantenna at 2. GHz, Wilco (a 2nd year engineering student from the university, doing vacation work for us) went to the local grocery store to see if he could find a can with the right dimensions. The cantenna has a long history of fanfare dating back to approximately 2002 when Andrew Clapp created the first Pringles cantenna. Shortly afterwards Rob Frickenger, a community wireless advocate, improved upon Andrew Clapp's. 802.11b Homebrew WiFi Antenna Shootout. I've been Slashdotted! The inner lining of a Pringles can looks metallic. Build your own Tin Can Waveguide WiFi Antenna (Cantenna). Create a cantenna to drastically extend your Wi-Fi signal! Works great with a router that has external atennas, like the old-school classic WRT54G. The aluminum can acts as a medium for the radio waves to be guided through. After we ate the chips he adjusted the design to fit the inner diameter of the Pringles can and cut it to the right length. The new design worked at 2. GHz. The inside of the can is lined with a thin aluminium sheet with a thin wax coating which saved a lot of effort ? He soldered the sma connector onto a small copper plate (shown in the next image) and attached it to the waveguide with two small screws after sanding off the wax coating on the inside to assure good contact with the aluminum. Sma connector soldered onto a small copper sheet. The following image shows the inside of the antenna with the connector and pin. We measured s. 11 and compared it with the simulation (see graph below) which had pretty good correlation. Extend Your Wireless Network with a DIY 2.4 GHZ WiFi Cantenna. Author: Mike Category: Antenna, Misc, Network 5 Mar 15. Extend you Wifi Network With a Cantenna. WiFi cantenna without pigtail by TheGoodLife in technology wireless. This adaptor connects your cantenna directly to a WiFi adaptor without need for a pigtail. A cantenna (a portmanteau blending the words can and antenna) is a homemade directional waveguide antenna, made out of an open-ended metal can. Although some designs are based on a Pringles potato chips can. Pringles Can Antenna Turns 10. Most industrial cantennas have a thin dielectric coating on the outside of the waveguide to prevent unwanted surface currents. We didn? t measure the dielectric properties of the Pringles can but it seems like a very cheap, practical antenna with 8 d. Bi gain and 2. 0% bandwidth at 2. Gregory’s site has a form that will calculate the frequency that your new “cantenna” will operate at.GHz. Inside of the Pringles cantenna showing the connector and pin. Author: ? Robert Kellerman.
