Huygens metasurface, an implementation of Huygens principle with metasurface, shows great potential in the manipulation of electromagnetic wave by elaborately designed subwavelength scale metaatoms with full phase coverage and high transmission amplitude. Here, a multiphase hologram with Huygens metasurface is demonstrated in microwave regime, and a novel algorithm method is proposed to modulate energy distribution among focal points. The proof‐of‐concept experiments show superior microwave holographic images with 89% transmittance efficiency, 59% imaging efficiency, and 1.65 root‐mean‐square error of focal intensity ratio. The proposed Huygens metasurface hologram expands the route to microwave applications for holographic technologies, including computer‐generated holograms, antennas, security, and data storage.
