Design of Metamaterial Absorber for 5G Applications

Abstract

In this paper, five resonant peak metamaterial absorber exhibiting more than 95% absorption has been proposed. The proposed metamaterial structure performs in the frequency range from S band to Ku band. The design consists of multiple geometries aligned together to form a symmetrical geometry.  The structure is based on a lossy FR-4 substrate with the dimensions of 10x10x1 mm. The simulation is carried out using CST Studio. The ultrathin, symmetrical and simple design makes the structure ideal for stealth, RCS, MIMO antenna for 5G applications.
