Wifi parabolic dish design

When finished,put it up and enjoy a very durable wifi antenna that provides long range and high bandwidth connectivity. Mount the assembled reflector and adapter in a window, on a balcony, or wherever there is a line of sight path to the desired wifi access point. For best performance, consider using a biquad feed. Other choices include using a colinear dipole, or using a 6" length of PVC to place a USB wifi adapter in front of the reflector. An alternative for systems notneeding huge amounts of gain isthe very simple - and smaller - linear parabolic on binarywolf.

It enables extended range Disclosure: AB9IL. Note : This parabolic grid WiFi antenna comes with your choice of the following connectors:.

RadioLabs — WiFi Flat Panel antennas, are an extremely low profile, high gain wireless antenna, allowing very high gain in a very moderately sized array. Similar in comparison and gain to a Parabolic, The only reason why these antennas are physically possible, is because this antenna operates in the 2.

A whopping 19 dB gain is achieved on both the transmit and the receive side and unlike a WiFi Parabolic Grid antenna ,. Take for instance this 19 dB, high gain Panel. If this antenna was designed for the much lower frequency FM Radio broadcast band for example, the wavelength is so long, that this antenna would be approximately 36 foot tall and 36 ft wide. BackFire Wifi Antenna- The backfire antenna has very good gain for such a small antenna.

Performance on 2. The 2. Thank goes to rimar for pointing out my lack of description. This thing isn't all that good looking but if you consider that I am getting a signal from my brothers house over yards from my apartment threw 2 walls made of dry wall. Across a major road. Threw his brick wall to his router.

Step 1: Calculations The first thing you are going to want to do is understand somewhat how a parabolic dish works. You can do a bunch of Googleing and reading and still not understand the mathematics behind wave angle, Illumination angles, etc.

Lucky for the not so math savvy some people smatter then me have done all the hard work in a multitude or simple programs. For my dish I have decided to go with 68cm diameter and a depth of 18cm.

I recommend you use metric CM to do all your measuring as it is easy to figure the lengths with the program. Naturally in this case the bigger the better. A larger dish will collect more of a signal. So if you feel frogy go right on ahead and make yours 6 foot. Input your Diameter and Depth into Parabola Calculator and hit calculate. It will draw with default setting a dish in blue and the focal length in red. Notice that when to hover your mouse over the black area you get a cross and some numbers X and Y will appear at the bottom of the window.

The numbers indicate the distance from the deepest part of the dish center out to the edge X and how deep they are Y. Step 2: Layout Taking the calculations from Step 1 you will want to lay out the curve of the dish on a flat surface. Accuracy is important but you can be off slightly and still have an operational dish.

First measure your width diameter and find the center point. Now go to Parabola note a point X, Y on one side of the dish. Then measure the bottom edge from the center out to one side. Our parabolic antenna is also directional, albeit less consistently.

In addition to the reasons listed above the length of our copper wire may also be responsible: since it extends beyond the focal point in both directions, signals which are reflected close to the focal point hit the copper wire as well, reducing directionality. Our DIY antenna is a success: while it is not as good as an off-the-shelf omnidirectional antenna it is certainly good enough to receive Wi-Fi signals over a range of m, comparable to a non-DIY cantenna.

It displays some form of directionality, if not a very good one. There are many possible improvements to this design. The easiest way to increase antenna gain and directionality is to increase its diameter. While mm is close to the maximum of the Prusa i3, it is possible to split the design into quarter dishes, assembling a dish twice as large.

Using a smoother material to cover the inside of the dish may also help. Finally, replacing the copper wire with a receiver only at the focal length of mm should increase directionality, at cost of a significantly more complex model.

A variety of other DIY antenna models also exist, such as the cantenna model we compared against, Wok-Fi using woks or similar kitchenware as antenna dish , and many more. And can be a fun side project! If you have any questions or comments feel free to reach out to me via my public inbox.
