| As the number of portable computing and | | | | In order to enhance the wireless capabilities |
| communication devices grew, so does the | | | | the antennas are developed and are now |
| demand to connect them to outside world. To | | | | available in the market, though they are easy |
| go on line the computers had to be plugged | | | | to install but these antennas are very |
| into a telephone wall socket. Requiring a | | | | expensive. Hence it would be a great thing if |
| wired connection to fixed network meant that | | | | it is possible to make our own antennas with |
| computers were portable, but not mobile. | | | | some readily available goods. We would need a |
| | | | cable (also known as pigtail) to connect |
| To achieve true mobility the computers need | | | | wireless interface card with the antenna. We |
| to use radio(or wireless in that case) | | | | would also need two kinds of connectors, a |
| signals for communication. . In this manner, | | | | N-male connector to connect one end of the |
| dedicated users would be able to read and | | | | cable to antennas and an appropriate |
| send email while driving or moving to other | | | | connector to connect the wireless interface |
| rooms etc. A system of portable computers | | | | card with cable. Since the making of antenna |
| that communicate by radio are known as | | | | requires wire, we would also need a soldering |
| wireless LAN. Therefore to provide mobility | | | | iron to solder wires. For more info see on |
| to the systems, wireless local area networks | | | | USB Wi-Fi |
| were developed and now a new technology | | | | |
| "Wi-Fi" or 802.11x(IEEE standard for wireless | | | | ADVANTAGES OF DESIGNING OUR OWN ANTENAS |
| LAN setup), has become the most popular | | | | |
| worldwide standard for the wireless | | | | The construction of our own antennas provides |
| communication in LAN.. | | | | various advantages to us. Apart from being |
| | | | cheaper than the antennas available in market |
| Nowadays all major Laptop manufacturers | | | | they are also easy to configure into our |
| provide an in built wi-fi system. Work is | | | | system. So instead of investing huge amounts |
| being done to make various devices like | | | | of money in antennas we can better manage |
| mobile phones, mp3 players etc to be wi-fi | | | | that money by adding them to buy better |
| enabled. | | | | Laptop systems. |
| | | | |
| In order to meet the growing demand for wi fi | | | | There is also time factor involved in making |
| networks, various public places are provided | | | | our own antennas system. Since it is easy and |
| with them. | | | | faster to make and install our own antennas, |
| | | | it saves lot of time. |
