Reconfigurable Surface Wave Fluid Antenna for Spatial MIMO Applications

This paper presents the design of a surface wave fluid antenna which can realizes beamshaping and spatial diversity for MIMO applications. The proposed design only required one RF input to achieve spatial diversity when comparing to the conventional multiple RF input ports approaches. The surface wave fluid antenna is designed for the millimeter-wave 5G mobile communications band from 24 to 28 GHz. The simulation results show that the radiation direction of the antenna can be controlled by changing the position of the fluid metal radiator.
