Waveguide antennas don’t use the director assembly the washery bitsand therefore are much simpler to build. It is also worth noting that this measurement is to be taken from the base of the can, not the ridge around the bottom. To test it out, pringlez your computer to a place where your Wi-Fi signal is usually very low, and point the cantenna in the direction your Wi-Fi signal comes from. Neither of these methods are ideal, and I would recommend using a stepping drill bit to make this part easier.

Once you have your precise measurement it is time to cut the hole. Perfect for when your own internet goes out and you want to be able to keep surfing in your slippers!

With these results, I’m convinced that the waveguide design is the way to go for cheap wireless networking. Wfii networking Radio frequency antenna types Antennas witi.

How To Make a Wi-Fi Antenna Out Of a Pringles Can

You may find that you get a better signal with the probe pointing sideways rather than straight up — if you can see the aerials on the router you are connecting to, try to mimic their orientation for the best results.

It’s the easiest antenna design I know of. Be careful whilst doing this!

The coffee can was a little short on length, but the 2cm it is lacking is still quite the difference from the 26cm of length the Pringles can falls short on. If this seems like something a little out of scope, another incredibly simple way to boost your Wi-Fi signal is to create a parabolic reflector to place behind it and focus the signal.


Scroll down for the next article. Cantennas can be used to increase cell antenna range, [5] improve reception, and decrease noise. Look out for cans with a 92mm diameter that are around mm in length, though you may find something exactly of that size hard to find!

The probe is the small piece of copper wire which will stick out into the middle of our can.

Cantenna – Wikipedia

I used a free piece of software called Homedale to measure the strength of the Wi-Fi signals I was receiving, in both cases you can see the cantennas blue line going off the top of the graph gave a significantly higher signal when compared with the internal Wi-Fi receiver of the laptop yellow line.

On Feb 11th, Rob, posted an article on his newest homebrew WiFi antenna – a tin can waveguide! This article has you covered. Where possible, a clear line of sight is best, though I found there to be a significant signal boost even pointing it through the thick walls of the old apartment building I live in. Reviewing his plan, I came up with different spacing that he Rob did. The 13 Best Raspberry Pi Projects of It is worth doing this regardless however, as you can expect to see great performance increases from this upgrade alone.

The various community wireless network groups all talk about them and folks are reporting that they do the job.

The Performance Summary The results surprised me! While folks are calling it a Yagi-Uda style antenna, the design of the driven prlngles in the Pringles can antenna looks like a Waveguide style design.

Cantennas may be used with other RF devices such as wireless security cameras. Getting Started With Blynk: It was followed by the Hunts Pasta Sauce, my modified coffee can, and the Flickenger coffee can in that order. The performance is good, the cost is very low and the skill required is minimal. The length of this probe is very important — and you need to be sure to measure from the bottom of the brass connector to the where the tip of the probe will be.

Published on the internet and in a fine book by Rob Flickengerthe net admin for O’Reillythis design for a do-it-yourself, VERY inexpensive antenna made from a recycled junkfood container is as cool as the other side of the pillow. The signal pringlds improvement is 20 dB, not 20 dBm.

Greg’s obsession de’ jour In my efforts to add the words “wireless savvy” to my network admin resume, I’ve been reading books and web pages on radio propagation, antenna theory and design, and building wireless networks with To see if I could improve upon the design, I built mine with corrected spacing. I’ve decided that Yagi design is not for the timid or non-radio-expert. Why would you want to make something like this?

For the battle, see Battle of Cantenna. My three waveguide designs, which utilized the pringled theoretical spacing, out performed the Flickenger Yuban coffee can handily. It seems that the design formulas for the waveguide design made a sizeable difference in performance. I decided to make both cans into cantennas — this guide covers the construction of the coffee can, though the construction is exactly the same for both, just with different spacing as per the calculating tool above.

Archived from the original on While there are many variations on this type of build, today we are striving for a balance of price and simplicity. In the yagis, it didn’t matter much.

In our test, the Flickenger Pringles can did a little better than my modified Pringles design. This method is a little involved, and may vary from router to router. Let us know in the comment section below! Formulas in hand, I started searching my cupboards for tin cans that fit the spec.

While waiting for some wireless equipment to come in, I started looking for wifk next antenna project. He reported good results – even better than the Pringles can design used by so many.
