A dual circularly polarized (CP) Fabry-Perot (FP) resonator antenna is presented in this paper. A linear to circular polarization conversion metasurface (MS) is employed as the superstrate of the FP resonator antenna. The working principle of the unit cell adopted by the MS enables it to independently control the transmission and reflection characteristics. Firstly, the MS is designed to present high reflectivity to ensure the high gain of the FP resonator antenna. Then the capability of polarization conversion is endowed to it. The square patch of the unit cell can receive two orthogonal LP waves, and the cross slot on the ground plane can also make them get through. Meanwhile, the circular patch with 45° tilted etched slot can radiate different CP waves when excited by different LP waves. Therefore, the proposed MS can combine the function of partial reflection and transmission polarization conversion. And for different LP waves, the MS can convert them into different CP waves. A dual LP microstrip patch antenna is designed to act as the feed of the resonator antenna. When the antenna is fed at different ports, different LP waves are excited in the resonant cavity and are converted into different CP waves by the MS, thus the antenna obtains dual CP radiation. The measured results indicate that the antenna can exhibit excellent dual CP radiation characteristic. Compared with other reported dual CP resonator antennas, the proposed antenna can obtain well performance with simple structure and low profile.

“…The reflective metasurface with the ability of polarization reuse has the potential to independently control multiple beams with different polarizations and beam directions, which can achieve polarization diversity and spatial diversity for MU-MIMO systems. Some independently controllable dual-beam dual polarization reflectarray antennas are presented using polarization reused reflective metasurface [7]- [13]. The key issue to realize independently controllable dual-beam dualpolarized metasurfaces is the design of dual-polarized unit cells, which can independently provide phase control for different polarized waves.…”

“…The single-layer square patch loaded with two delay lines can also be used to independently control reflective phases, which has reconfigurable potential by changing the length of the two delay lines [8]. Furthermore, for dual circular polarizations, the Berry phase compensation and dynamic phase compensation can be implemented to achieve the independently controllable dual-circularly-polarized unit cells with wide working bandwidth [12], [13], but the method is difficult to realize for linearly polarized unit cells.…”

A broadband dual-polarized single-layer 1-bit unit cell is proposed for achieving the independently controllable dualbeam reflectarray antenna. The unit cell independently provides two-state phase compensation for two orthogonally linearlypolarized waves. The 180-degree reflective phase difference between the two states is achieved by tuning the magnetic resonance of State 0 and the electrical resonance of State 1. With its two resonances close to each other, the unit cell has a reflective phase difference of 180 ± 20 degrees between two states over a broad bandwidth of 27.2-51.1 GHz. The cross-polarization levels of below -30 dB ensure the high isolation between two polarizations. Using the proposed dual-polarized unit cells, a 1-bit dual-beam reflectarray antenna is designed and excited by a dualpolarized horn to show the ability of independently controlling two orthogonally linearly-polarized waves. At 33 GHz, the beams direct to -15 degrees and 20 degrees for the feeding of horizontally and vertically polarized port, respectively. The 1.5-dB gain bandwidth is greater than 20% for both polarizations. The proposed dual-polarized reflectarray antenna with independently controllable 1-bit dual beams provides an alternative design for the multiuser multiple-input multiple-output applications.
