A beam-forming network based on Butler matrix is also implemented to scan the radiation beam along a target area in the near zone, which may improve the energy efficiency and reduce the multipath interferences. The design approach, numerical simulation and experimental measurement over an antenna prototype in the applications of radio-frequency identification are presented to validate the feasibility. © The Institution of Engineering and Technology 2015. |
