A study on signal reception of grid antenna for wireless network

Abstract

Wireless LAN technology or WLAN is gaining in popularity due to it's facility and mobility. The WLAN technology makes connecting devices within the home or office together without the need of cabling. Both desktop computers and handhelds can freely connect to each other or connected to the network from the area in wireless signal area. Since the signal of the wireless network spread in the air and is not restricted only in a room or a small area. At present, we can connect between remote area networks together by using wireless bridge to expand the service network. Because the network demand for network services in some areas can not be provided, wireless bridge system is required for connecting and expanding the service of WLAN. To solve such problems, we have analyzed, tested, improved the quality of the WLAN antenna for better performance and developed the ability to send and receive signals with long distance and good signal distribution by choosing low- cost and suitable materials to meet the users' requirement with less cost. From the experimental results, it could be concluded that the different materials used as a reflective plate affected the performance of the antenna in both the intensity and the distance between the transmitter and receiver. The researchers then concluded that the antenna performance was based on the electrical conductivity of the material of the reflective plate. The dish with reflective plate of aluminum foil provided better performance than the dish with reflective plate of zinc and cotton, respectively.
