Design and development of antenna for wifi system

Abstract

In this project, a 4x1 Rectangular Microstrip Patch Array Antenna at frequency 2.45GHz for Wireless Local Area Network (WLAN) will be designed, fabricated and tested. The antenna will be design base on optimization and characteristic analysis. Some method for optimize the Microstrip Patch Antenna are studied and implemented to produce the desired antenna. The objective of this project is to design a high antenna gain for particular purpose which is 10 dB and directional radiation antenna pattern. Theoretically, the objective of this project can be achieve through the use of high quality substrate such as Taconic TLY-5 which is have low relative permittivity or dielectric constant and higher substrate that will improve the bandwidth. This is due to the Rectangular Microstrip Patch Array Antenna which the bandwidth is determined by the electric constant and the height of substrate. Low loss-tangent will increase the efficiency of the antenna. The patch array also has a better directivity than the single patch. The antenna was fabricated based on simulation and measured using Agilent E8362B Network Analyzer. The expected result from this project is the antenna will has a high gain, better directivity, larger bandwidth and high efficiency
