Antena grillada wifi 2.4 ghz

The "driven element" in a Yagi antenna, is usually the second one from the start. It is a broken loop and not a straight wire. A loop of wire resonates at a specific radio frequency depending on its dimensions.

The dimensions of the driven element in this antenna is set at 2. It just happens that its about the size of a common big paper clip. You need to clip the paperclip so that it loops around and meet in the center but the end not touching, leaving a gap see photo. Fix it in place with crazy glue and build the back bone around it. When all the elements and sticks are in place, reinforce the antenna with another layer of popsicle sticks. Glue full lengthed popsicle sticks on top of the antenna.

The antenna should become mechanically stiff. Then rip the paper template of the antenna. This is the most difficult part and depends on the electronic hardware you have. The basic idea is that you need to solder a wire between the WiFi board's RF output and the driven element of the yagi antenna. Those with external antennae, like mine, are easier to connect because you are just replacing the external whip antenna with the Yagi.

Those with internal antenna may need to have their on-board strip antenna modified as illustrated in the pictures here. You need to slightly experiment in this case. I have tried soldering a coax to my board's antenna connectors and the two ends of the yagi's active element loop but it did not work in my case. I have no explanations why that did not work, but other DIYers that have built Yagi antennae connected their antenna in this manner.

In my case, I just connected a single thin strand of copper wire between the active element of the strip antenna and one end of the loop of the driven element. Please read the annotations of the pictures for more details. The performance was pretty spectacular for this easy to build antenna. I was able to see the WiFi of a hotel that was 2 miles away from my home.

The most difficult part was connecting the antenna to the USB modem. Okay well I read through the entire post and I saw many things that made a lot of sense, also saw a lot of unnecessary flaming, but I do have a few comments to make. Right off the bat the one individual that asked about having his modem in the basement with a rotating antenna on the roof needs a reality check. Take the dongle apart and connect a USB extension cable to it and mount it directly on the antenna assembly.

Paper clips vs copper, at this frequency it's not going to make much difference, however the specific model was generated using 14awg copper.

Someone said glue it all to cardboard then cover it with more cardboard actually a strong and stable design, original author said build around popsicle sticks wooden , both are subject to absorbing moisture from the air and either can have a poor dielectric constant, I would suggest some kind of plastic they make popsicles with plastic sticks.

The lengths of the elements, the spacing between them, and keeping them all in the same plane and parallel to each other is the most important consideration. If you use the folded dipole make sure the folded part is perpendicular to the plane of the rest of the antenna and use ohm twin lead to connect to the dongle, but your SWR will probably be much higher, reducing your effective gain and possibly resulting in early failure of the dongle.

Horizontal vs vertical, after you have your antenna connected and have connected to some network you can try rotating it about its horizontal axis to see if you can get a better aspect on the other antenna more bars. All in all though good job to Biotele, it's cheap, it's easy, and if done right will provide excellent results.

I did not build this antenna, but I built 2 antennae very similar before reading this post, My son and I live almost 2 miles apart and either of us can stream p movies from the other's house during a thunderstorm. Reply 1 year ago. Was the setup with your son line of sight, or was there any foliage between you? Was this able to extend the original wifi network to the second location?

Reply 7 years ago on Introduction. Thanks upon this project. For my recommendation, I would advise you to use a usb to Ethernet adapter then feed your router with Ethernet as usual. I'm a ham radio operator and have build many yagi antennas and am going to build this one. Here's a suggestion. By aurel , April 21, A Simple Patch Antenna 1 2 3 4 5.

So it may well be that the range in the different directions is different due to the particular circumstances. The opening angle is smaller than in the omnidirectional antenna, while the signal strength is higher, but of course not as high as with a special directional antenna.

It is always used when large areas are to be supplied with a WiFi signal, for example several buildings, a campsite or an event site. To obtain the ??

The range of the signal is indicated by the dBi number, the higher this is, the further the sector antenna transmits. For a standard WiFi network antennas with 2.

In the 5 GHz frequency band, they are mainly used in office buildings, because at this frequency the susceptibility to interference but also the range is slightly lower than in the usual 2. Especially for large and open spaces they are the best choice. Compare items. Create wish list. WiFi Antennas.
