Abstract
Wireless communication systems have seen remarkable advancements in recent years, driven by the ever-growing demand for high-speed, reliable connectivity. Reconfigurable Intelligent Surfaces (RISs) have emerged as a promising technology to address the challenges of wireless communication, offering unprecedented control over electromagnetic wave propagation in various environments. In addition, RISs can be fabricated with low cost and can be controlled easily by the user. Meanwhile, RIS has wide adaption to the optimization algorithm, low power consumption. With all the advantages RISs can provide, it has been considered as one potential area that could lead the wireless communication into next era. This thesis develops one type of RIS based on the prototype design from Arizona State University [1]. A two state, 25 elements RIS, has operating frequency at 5.8 GHz, is designed and simulated by using full-wave simulator. The unit cell of the prototype design can be controlled by using a RF switch, which can switch between two states, [0, 180], to change the reflectivity of the surface to apply a 180-degree phase shift for the wave. Since nowadays the wireless communication systems for public use (Wi-Fi, cell phone network, and etc.) has operating frequency at 5 – 5.8 GHz, the prototype designed is capable to use to enhance the performance for those systems. Moreover, the prototype design can be fabricated and implemented on PCB board, which further minimizes the difficulties and cost for the implementation of the RIS.
