摘　　要：This paper presents a review of transmitarray(TA)and reflectarray(RA)antennas based on the magnetoelectric(ME)dipole antenna struc-ture.First,the basic operating principles of ME dipole,TA and RA antennas are introduced.Next,ME-dipole-based TA and RA designs are discussed,with four antenna designs presented in detail,including two fixed-beam TA designs with high aperture efficiencies and two reconfigurable designs with a beam-scanning capability.The techniques involved in these designs are also analyzed to provide insight into the ME-dipole-based TA and RA designs.The simulated and measured results of the reported prototypes show that the introduction of the ME dipole antenna significantly broadens the band-widths of the TA and RA antennas not only in the fixed-beam designs but also in the reconfigurable designs.The ME-dipole-based TA and RA designs reported in this paper are compared to highlight their benefits and limitations.Future possible research directions and challenges are also discussed.
