The latest technologies are so firmly entrenched in the life of every modern person that few people imagine their day without using them. One of the most progressive industries, the development of which is proceeding rapidly, is the sphere of wireless networks. Wireless telephone communications, as well as access to the Global Network without reference to a stationary workplace, have already become commonplace and routine, meanwhile introducing tangible convenience and increasing the level of labor efficiency of a person, as well as increasing the level of comfort and pleasure in the process of entertainment that we got today digital name. In turn, one of the leading technologies in this aspect is Wi-Fi - the basis of wireless networks that have spread everywhere. In our country , Wi-Fi access points can be found everywhere - they are used to organize networks on the scale of many companies, in small apartments and large mansions, with their help free Internet access is available in crowded places, etc.
Of course, the realities of life in our country determine the difference between our fellow citizens and residents of other countries, and the use of Wi-Fi was no exception. For example, the high cost of devices, the remoteness of users and equipment designed to receive a Wi-Fi signal from access points, and many other factors lead some to think about how to make a wifi antenna yourself. Such a DIY wifi antenna made of affordable and inexpensive materials is designed not only to increase the level of signal reception from the access point, but also to do it with minimal cost and effort. A homemade wifi antenna can help if you use non-standard or outdated equipment for reception, or there is a need to receive a wifi signal in such hard-to-reach places where the possibility of acquiring a special antenna is simply not available.
Do-it-yourself wifi antenna - is it possible? It turns out to be not only possible, but also widely used on the territory of our state. You can do this in dozens of ways - various home-made devices adapted for different purposes are quite common. On the Internet, you can find a whole list, consisting of wifi antenna designs created by craftsmen who used knowledge in physics, knowledge of the features of technology and improvised materials. We will not dwell on the complex designs that a wifi antenna can represent with our own hands, but consider the simplest of them.
So, do-it-yourself wifi antenna made from a tin can (!). This invention is suitable for wireless networks operating according to the 802.11b standard, and it may also be suitable for use in other cases where these frequencies are used.
For manufacturing, you will need a tin can, an N-type mother socket, a pair of small screws, as well as a piece of copper wire with a diameter of 2 mm
The tin can can be from under anything, but its walls should be smooth, that is, not corrugated, and the diameter should be in the range of 7.5-10 cm and the height exceed 13 cm. The optimum diameter is 9.2-9.5 cm .N-socket can be purchased at any radio components store, or obtained from damaged equipment. A copper wire with a length of about 3 cm can be obtained by stripping any wire used in electrical work, if only its diameter is 2 mm.
Production should not cause difficulties. The wire is soldered to the central pin of the socket. After that, a hole is drilled in the wall of the can, the location of which will have to be calculated using simple calculations and knowledge in the field of physics. The distance from the waveguide, which is the copper conductor to the bottom of the can, should be approximately ¼ of the wavelength of the conductor. After calculating the distance and drilling a hole, a connector with a soldered conductor is fixed to the wall of the can. At this manufacturing can be considered finished. It remains only to determine the direction in which the antenna will be oriented, and you can begin testing.
