Abstract

A wireless channel control concept based on spatially, i.e., position adaptive antenna arrays is introduced. This technique simultaneously utilizes beam-steering and spatial adaptation to enhance the wireless channel gain and system capacity. The concept is inspired by the microfluidically reconfigurable RF devices as they can enable compact systems with spatial adaptation capability. Specifically, a five element linear 28 GHz mm-wave antenna array design that can achieve beam-steering via phase shifters and spatial adaptation via microfluidics is detailed. Simulated realized gain patterns at various array positions and phase shifter states are subsequently utilized in link and system level simulations to demonstrate the advantages of the proposed concept. It is shown that a wireless communications system can achieve 51% improvement in the mean signal-to-interference ratio due to the spatial adaptation capability.
