  ABSTRACT: 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 integrated metasurface, enabling the integration of CP Fabry-Pérot cavity antenna (FPCA) and CP folded reflectarray (FRA), while preserving circular polarization purity and delivering high gain performance. In this design, the PRS acts as the reflector for the FRA at 8 GHz, while the multifunctional metasurface serves as the reflector for the FPCA at 8 GHz and provides phase compensation for the FRA at 13 GHz. Consequently, the FPCA and FRA can share the same aperture with high aperture reuse efficiency. The antenna achieves high gain across both frequency bands, with peak gains of 19.4 dBic and 22.8 dBic, respectively, without complex feeding networks. Leveraging the advantage of low focal-length-to-diameter ratio of the FRA, the array’s profile is reduced, with a height-to-diameter ratio of only 0.46.
