A Study of Conformal Metasurfaces on Passive Beam Steering for Arrays

Beam-steering has drawn significant interest due to the expansion of network capacity. However, a traditional beam steering system involves active phase shifters and controlling networks which can be complex. This work proposes a passive conformal metasurface design on beam steering. The phase shifting is achieved by changing the curvature of a conformal metasurface. In addition, three conformal prototypes were fabricated and tested using different techniques such as 3D printing. The simulations and test results indicate up to 20? of beam shifting. This study can be extended to higher frequency bands for lower power consumption beam steering systems
