THE DESIGN AND CONSTRUCTION OF AN ANTENNA BOOSTER ( chapter 1-5 )
Wi-Fi signals are susceptible to signal loss as they travel hence Wi-Fi users are rarely completely satisfied with the signal strength offered by the off-the-shelf Wi-Fi cards, routers and access points. This project research intends to introduce a new design to a device which can provide Wi-Fi users with high signal strength and at a lower cost in order to enable them have a seamless, uninterrupted and
reliable communication. To implement this, a biquad antenna, a booster circuit and a USB connector were constructed and a Wi-Fi booster system was formed by interconnecting these three circuits together.
The function of the Biquad was to receive signals, these signals was then sent to the booster for amplification after amplification the signals passed through to the USB connector circuit which adapted it to a USB connector which is plugged into a computer. Using software to analyze the throughput and signal strength showed a repeated 12dBi gain. Further test showed that signals which could not be captured by the in-built wireless card of a computer system were captured with this device.
CHAPTER ONE: INTRODUCTION
An antenna booster is a device which is designed to amplify reception or received signals so that a marginal signal can be utilized. The way the antenna booster works is that it expands the area of the antenna, allowing it to pick up more of a weak signal and then translate it into a stronger signal for the device that the antenna is attached to. Antenna boosters can be used to improve radio signals in
any frequency band be it the Very Low Frequency (VLF) band or the Extremely High Frequency (ELF) band….
