FSS Incorporated MIMO Antenna for 5G and Wideband Applications

An advanced, effective, and novel antenna array is presented in this paper. To improve the antenna's performance, a multilayer frequency selective surface (FSS) was integrated. This suggested FSS is accomplished utilizing periodic split-ring resonators (SSR). This multilayer FSS was superimposed over the antenna at a height of 5mm from the ground plane of the antenna. This gap created the fringing field, which reluctantly improved the characteristics by 15dB. A wideband of 27GHz was achieved for which RL is less than −10db for the entire range of frequencies. The proposed antenna is designed for 5G applications.
