- Clear Cantenna Yagi Long Range 2.4ghz Wifi Antenna Price
I'm designing a high gain (18dBi or so) 2.4GHz antenna for use with 802.11 hardware. I decided on a Yagi design as I wanted something that takes up little space in a bag.
Instead of wire elements extending out of a stick like a TV antenna, I'm thinking of taking a wooden (or plastic?) board, cutting grooves in it, and pressing copper wire into the grooves. Are the calculations different if I were to embed the elements in wood? Dry wood is an insulator but its dielectric constant is much different from that of air. As of current, my 25 element design is going to be on a board that is 3' long and 3' wide. I'm thinking of cutting it in half and adding a hinge so it folds to a more reasonable 1.5' length for carrying.
Am I correct that I'll need a hinge or other mechanism made of a nonconductive material to avoid affecting antenna performance? I'm going to use homemade Litz wire to increase the efficiency, so they'll be even more fragile than solid wire. My antenna theory is rusty at best, but do you really need 18db gain? The reason I ask is that a collapsible corner reflector antenna would meet the compact, folding and easy to make feature, but only about 12db gain to the front and 20db rejection to the rear. The most efficient design when you get up in the 2.4ghz and up range is a small parabolic dish. Easy to get lots of gain with not much material and fairly compact. Your wooden/plastic idea could be made to work, but at those frequencies.
Relative humidity would become an issue and might create tuning headaches. I'd let my fingers do the walking in google, there's plenty of Ham Radio references on antenna design in the 2.4ghz range and up. Phase 3D (a large elliptical orbit satellite built by hams) had a 2.4ghz down link and decent gain was important to hear that satellite so there was lots of home brew antennas cobbled together for that. I dropped out of the amateur satellite arena about 10 years ago. So I'm not up on the latest. Amsat.org might have some useful information as well.
Regards Christian. Like psi mentioned above, 2.4ghz is very difficult to get right without proper tuning gear!
A 18db yagi at 2.4 w/o tuning gear. I personally wouldn't try it and I have 2.4 measurement equipment. I like hero's suggestion of printing & etching the antenna! I know the moxon doesn't give you the best numbers on paper, but it's design allows for much tighter tolerances for diy, no balun required, sma/n/whatever to be soldered directly to the board.
Heres a 2.4 yagi for $12usd if you have enough time for shipping from china. Tough to build one cheaper than that!
Patch antennas are portable and pretty easy to fabricate. 16db printable patch antenna the 'cantenna' is another easy build with potential for high gain. My 2¢ fwiw, -sj. Here it is the simple calculation. The problem is that of the propagation into a waveguide, so wavelength is not the same as for a wave traveling in the open-space, and depends on the mode involved.
Each mode (field conformation) has its wavelength (and propagation speed, of course). Then the ideal situation is when there is only one mode propagating, so above a certain minimum frequency and below a certain other, which are a function of the diameter of the cavity.
Since the back of the can (closed side) imposes a zero to parallel electric field, positioning the pin at a distance equal to one quarter of the length lambdag gives the best result (emitter antenna is into a point of maximum field strength). Imposing the minimum and maximum frequencies to stay in between the mode and second mode cut-off: a = d/2 1.83 / (2.pi.fmin.sqrt(mu0.epsilon0)) above the first mode cutoff a = d/2.
Improving WiFi Speed and RangeHow to improve or optimize your WiFi connection? Regardless of whether how older your router seems to be, these tips and tricks work for everybody. Here is a list of worlds best long range which can be used to increase WiFi Speed and Range.
High Gain WiFi Antennas / Long Range WiFi AntennaThe first thing you want to try is to adjust your antennas or possibly buy an external WiFi antenna or a high gain WiFi antennas. Now by just saying your antennas, your mileage may vary. If your antennas are pointing vertically the WiFi signal is going to go out more horizontally. If your WiFi antennas are pointing horizontally the penetration is gonna go upwards and downwards. If that doesn’t work which most likely won’t for most people the other option is to buy an external WiFi antenna. I recommend looking at a high gain WiFi antenna or a Long Range WiFi antenna that will give you high speed internet connectivity. This works only if you can actually unscrew the current antennas that are attached to your router right now.
High gain WiFi antennas / Long range WiFi antennas are a lot more potent and will allow you to push the signal further, which will give you very high speed WiFi and internet connection over a wide range. This will help you increase the WiFi range. Try this Before Buying new Antenna (May be this will solve your problem). 3.

Let’s install the router sometimes routers get shipped out with firmware that’s kind of glitchy and then a few weeks later or a few months later they release new firmware to update those glitches. Sometimes those glitches cause Wi-Fi problems.
So the best thing to do is log on to your router using your bid username and password, which I hope you change when you first got your router, check the status or the about page of the actual router itself to see what version of firmware that your router is currently using. Then visit the manufacturers website to find out what the latest version of firmware is for your router. Download, install and see if that solves your problem. Changing WiFi ChannelThe third thing you could do is change the channel for your router or your access point.
Now the way your signals travel across an open areas through frequencies. Most routers support two different frequencies – the 2.4 gigahertz frequency and the 5.0 gigahertz frequency. If you’re using an older router that most likely it only supports 2.4 and that’s usually common with 802.11 B and G. Now, if you’re using a newer router that supports 802.11 n or AC then you’re gonna have backwards capabilities to support 2.4 and be able to use the newer frequency of 5.0. This is for the people who are using an older router. Placing the RouterThe fourth thing we need to consider is a.
A router broadcast signals in every single direction. So imagine like a globe or sphere surrounding that router. If you’re inside that area, you’re actually going to receive a WiFi signal; if you’re not you’re not going to receive.
So the best place to place that router is somewhere in the middle of the house and if you really could hang it from the ceiling.The next best option would be place it on a desk or wall-mounted on the side of a wall. Just make sure that wall is not load-bearing. Also avoid putting the router on the floor inside a cupboard or an enclosed area. Think of the router as a plant, it needs sunlight, it has to breath.Avoid placing the router beside materials that contain stone concrete or bricks as these types of materials don’t allow Wi-Fi signals to penetrate them too well.
How Long Range WiFi Antennas Work?The WiFi Antenna WireConsider a normal power cable. Notice that the lines are parallel to each other. Now imagine a High Gain Antenna coaxial cable. You’ll notice that there’s a shield on the outside and then there’s an insulator and then there’s a center conductor.The center conductor of the External WiFi Antenna is actually what runs the power to the antenna. So if you have two pieces of wire side by side in parallel, you will have a current flow in the forward direction and through the other wire current flows in the opposite direction and the current flows cancel each other out.If you have a piece of coaxial cable, which is actually grounded on the outside and the current flows in this direction and the current flows in the opposite direction on the inside and the currents cancel each other out.How does an antenna work then?
Consider a simple dipole antenna like you put on your FM stereo at home. The WiFi antenna is just two wires in parallel split off over in two direction.This way, the current will be flowing in same direction at the plane it is split off. This allows us to generate RF energy that leaves like wave. New to?We have a beginners guide on “ ” which will give you a kick start in this field.
