Based on the Pringles can diameter (7 cm), the ideal length of this pin is about cm . It is always just shy of the middle of the can you are using. Step 3: Building the antenna We make a hole about cm (length based on testing performance ) from the bottom to the top of the can. We then insert and stabilize the.
Read this chapter and if you want to know more, pick up a copy of the book today! In This Chapter:. While there are many commercial antennas available on the market today, they can be expensive.
There are several different types of antennas that antenja can build. The most famous Wi-Fi antennas are made from either a coffee can or a Pringles potato chip can. In this chapter you learn how to build your own antenna from a regular, metal coffee can.
You will be able to build it quickly and cheaply. As an added bonus, you will have lots of coffee which will come in handy in staying awake for the other projects in this book. This site may earn affiliate commissions from what causes burning in my legs links on this page.

How To Make a Wi-Fi Antenna Out Of a Pringles Can. DIY solutions to extending Wi-Fi have existed for as long as Wi-Fi itself has. Ingenious internet users have been using everything from kitchen foil and fo. Saved by MUO - Technology, Simplified. Aug 08, · UPDATE* After more trial and error, I realize that my original Pringles Cantenna was built too far back into the can this newer calculator suggests a dist.
So first thing to do is go to the cantenna calculator and enter the diameter of the opening of your can in mm. Alright then what we want to do is remove the top of one can and the bottom of the other. Once you have done this on the can with the top removed cut out a small strip approx 10mm across and 15mm down the can.
Next we need to heat up our soldering iron as we are going to solder these cans together, You want your iron HOT I put mine on around C and this seemed to work great. First thing is to tack the can in place with a few small solder joints then make sure your cans are straight and run a good solder bead all the way around. Once the solder joint cools you will see the inside of the can is a bit raggard and raised.
For this I just got a large socket on the end of an extension bar and used it to hammer the raised edge down, with a bit of work you can get the inside of the can fairly flat. Next from your calculator measurement find the height of your main element, Cut a piece of copper wire this length and solder to the top of the f-type connector as shown below.
At this point you have a working cantenna , Connect your piggy tail between it and your wifi card and you are good to go. Remember this is a directional antenna so it needs to be point in the direction of the AP your trying to connect to. Now what about this stand business, this really was me just mucking about but it turned out to be quiet useful. What you want to do is take the bottom of the tin you cut off and cut three small triangles out of it evenly around its circumference, bend the remaning triangles down to make a sort of tripod shape.
Then you want to bend them in the middle so the corner of each triangle touches then solder them together, now just solder it to the cantenna. This might seem a bit silly but it really helps when trying to point the antenna and it costs you nothing. Alrighty your probibly wanting to know was it worth the effort well for me yes.
I have not had a chance to do exensive testing, but from some basic testing it seems to be giving me a 15db increase over the stock d-link antenna which is certainly a massive increase for the minimal cost of the build.
Question 11 months ago. I have made a project of Wifi extender using pi zero w which is much simpler than this instructable. Also you do not need to install any additional packages.
Is the a possible way to make this connect to an AC Outlet? I've used a similar design myself with good results. Impedence matching is an important part of the design. The whole of the transmission line, includung the antenna requires impedence matching. Using some rf decouplers and high frequency diodes and an oscilloscope it is possible to measure the SWR.
A good match between your antenna and transmission line will result in a low reflected wave. If the reflection is high compared with the foward wave there is a bad match, poor performance will result and the dimensions of the antenna would need altering. Reply 8 years ago on Introduction. If impedance of the antenna is too high or too low, the transmitter router will see the antenna as ah dead short resulting in high SWR that can burn up the final amp in the router transmitter.
So impedance matching is Very important. I want to try this out but the cantenna calculator is lost??? The link doesnt open the calculator.
Sorta like the pringles cans I have seen around. I wonder if having a smooth interior or the ribbed kind affect the signal in any way. Also, I don't use the coax connector for my wifi. I have a USB adapter So i would have to adjust this somehow. Reply 9 years ago on Introduction. Reply 10 years ago on Introduction. Dude, this one is so easy to do. I wrapped a 1" band of aluminum around with 3" of handle below. I have built every one of these Wifi antennas.
Sounds really good How about an instructable????! Go here: www. Luch, Mr Steve. Posting another completely different website on how to make the exact same thing is more than a little rude. Particularly when you add insult to injury by saying "its teh[sic] best site of all. And this instructable is far superior. I've never built one of these before, but as to your question about the coax connector, if your USB WiFi adapter has an external antenna connector, you'll need a coax jumper with the same kind of connector as is on your WiFi adapter.
If you're adapter lacks an external antenna connector then I'm not certain how you'd be able to do this. You'd still need coax and you'd need to crack open the WiFi adapter and locate the antenna. Find where it connects to the board and solder the center conductor of the coax where the antenna connects and the coax shield would need to connect to ground.
Assuming you were able to identify where to solder the coax, and are skilled enough at working with surface mount boards, it MIGHT work. However, you're just as likely to ruin your adapter. Working with antennas isn't just a simple matter of hooking it up. A transmitter is designed for a specific impedance, measured in ohms. I'm not going to go into a treatise on antenna theory. A transmitter is designed to use an antenna system that has a specific impedance.
If the antenna system's characteristic impedance doesn't match the transmitter, then you have an impedance mismatch which can, if the mismatch is too large, cause physical damage to the final transistors in the transmitter.
Thanks for your replys, as far as the ribbing on the can I dont thing this is an issue because if you look at the opening of the can there is actually a lip which I think will compensate for the fact the inside isnt smooth.
Also with the impedence if you use the correct 50 ohm cable etc the impedence should be fine also the transmitter should have an impedence matching circuit to prevent damage. Some of the usb wifi adapters can have an external antenna connector added as ive done this before but your right you have to be real careful. Reply 9 years ago on Step 6. Nice stuff. As I am on budget and want to connect with my friend with wireless I am thanking you for this post and I am off to create the cantenna.
By budgethackdotcom Budget Hack - On a shoe string Follow. More by the author:. This antenna is one of the easiest and cheapest things you could build to extend the range of your wifi network. Most of the materials are probably sitting in your cupboard right now so it really can be built on a shoestring budget.
Last thing to do is have a look at your calculations again you can see the distance the element should be from the back of the can, measure this out on the can and drill a hole big enough for it to go through. Once the mount is in place go around and fully solder it to the can like in the image below. Did you make this project? Share it with us! I Made It! Answer Upvote.
