A single‐layer stub‐loaded terahertz resonator is presented for constructing reflectarrays with enhanced bandwidth in article number 1900791 by Xiaolong You and co‐workers. A focusing reflectarray that transforms the incident collimated beam into a focused beam is realized using this resonator as a building element, exhibiting improved bandwidth as intended. The reflectarrays constructed by this resonator can be applied for various beamforming functions with applications in terahertz communications, sensing and imaging.
