A low-profile dual-broadband dual-circularly-polarized(dual-CP)reflectarray(RA)is proposed and demonstrated,supporting independent beamforming for right-/left-handed CP waves at both K-band and Ka-band.Such functional...
This paper proposes a low-profile, aperture-shared dual-band bidirectional circularly polarized (CP) antenna. The design incorporates a partially reflective surface (PRS) and a multifunctional transmission-reflection ...
