Abstract

Wireless communication has experienced an enormous growth since it allows users to access network services. WLAN is the most rapid evolution and wide popularity in standard developed by IEEE (Institute of Electrical and Electronics Engineers). The 2.4 GHz and 5.2 GHz frequency is user in WLAN network. This project presents the design of geometrical array using microstrip antenna. The special of requirements microstrip antenna required it for designing the array concept. It is also one of the fastest growing segments in the telecommunication industry. It have proved that the microstrip antenna have their own unique characteristics that improved the telecommunication industry. Design geometrical array microstrip antenna can achieve the higher gain and broader bandwidth. The project design using three types of geometrical antenna, such as rectangular patch, triangle patch and circular patch antenna. The antenna is designed at the frequencies 2.4 GHz, 5.2 GHz, and 5.8 GHz. The behavior of each type antennas are investigate such as return loss, radiation pattern, bandwidth, half power bandwidth (HPBW), first null bandwidth (FNBW) and gain. The project are includes the simulation process, fabrication process and testing. According to the single element, triangle shapes show the efficiency of return loss of -27.02 dB and largest percentage of bandwidth. Circular shape shows the higher of gain. In array configuration, the 2 x 4 array of rectangular shows higher of return loss compare to 1 x 2 and 1 x 4 array configuration. The 1 x 2 and 1 x 4 array configuration shows that circular shape shows the good of return loss, higher in gain and percentage of bandwidth.
