DESIGN AND OPTIMIZATION OF A FOUR-ARM METAMATERIAL REFLECTOR FOR HIGH REFLECTIVITY

Abstract

We are examining a four-arm metamaterial reflector whose frequencies are ranging between 1 to 25 GHz. As the name suggests, this reflector is a four-arm structure built up of copper arms and a FR4 substrate. This design is further intensified using COMSOL in order to achieve excellent frequency and minimal loss over the given frequency range. Thus, the results of this suggested reflector show a high level of reflection which is 88.97%. Some of common applications of this suggested reflector are Antennas, Radar Systems and Wireless communication equipment’s. In a nut shell, this reflector offers a simple and efficient method for obtaining high reflectivity and low loss in a compact and lightweight container. Also, the suggested design is a promising choice for further research and development in the field of metamaterials.
