Abstract
In order to simply broaden reflection beam of metasurface, the utilization concept of multi-sheet configuration is presented and investigated. Demonstration is based on four sheets of 28.25 GHz metasurface that have the same designed incident angle. Meanwhile, their reflection angles are designed to be moderately different for producing broad reflection beam. In full wave simulation, the combined metasurface perform broad-beam operation in corresponding to individual reflection angle of each metasurface. Then, in coverage area measurement of local 5G system, multi-sheet metasurface provides wider coverage with compact installation space comparing to conventional metallic reflector.
