This paper presents a design of lens antenna in wireless communication system. The main focus of this project is to design lens and analyze the lens behavior in lens antenna. Besides, the factor that influence the design of lens and gain of lens antenna is investigated. Antenna is use to receive and transmit signal. Antenna with high gain will allow good signal to be transmitted. However, conventional antenna has low gain. Therefore, to increase the gain of the system lens antenna is designed. The performance of system gain is monitored. Simulation is performed in CST Microwave Software. There are three basic shape of lens is studied in this project and the lens are flat lens, concave lens and convex lens. Preliminary work is done in order to find out the best lens shape that will provide the higher gain.
