Abstract

A broadband high gain metasurface-based Fabry–Perot resonant cavity antenna (FPRCA) for polarization reconfigurable is proposed in this article. The antenna features a microstrip source antenna with a single-layer 2 × 2 circular patch metasurface, a ground plane, and a double-layer partially reflective surface (PRS), along with four resistors and two diodes. Characteristic mode analysis (CMA) is performed on a 2 × 2 circular patch metasurface, and the design is optimized to ensure that the characteristic currents of its modes are orthogonal, enabling effective excitation of circular polarization (CP). In addition, further research through CMA has found that adding loads can change the direction of current orthogonal to each other,... (More)

A broadband high gain metasurface-based Fabry–Perot resonant cavity antenna (FPRCA) for polarization reconfigurable is proposed in this article. The antenna features a microstrip source antenna with a single-layer 2 × 2 circular patch metasurface, a ground plane, and a double-layer partially reflective surface (PRS), along with four resistors and two diodes. Characteristic mode analysis (CMA) is performed on a 2 × 2 circular patch metasurface, and the design is optimized to ensure that the characteristic currents of its modes are orthogonal, enabling effective excitation of circular polarization (CP). In addition, further research through CMA has found that adding loads can change the direction of current orthogonal to each other, thereby achieving the polarization reconfigurable characteristics of the antenna. The designed double-layer PRS generates a positive reflection phase gradient and can radiate CP waves. The proposed unloaded device antenna achieves a −10-dB impedance bandwidth (IBW) of 20.6%, a 3-dB axial ratio bandwidth (ARBW) of 17.2%, a peak gain (PG) of 12.0 dBic at 7.7 GHz, and a 3-dB gain bandwidth of 19.7%. By connecting 100-Ω resistors, linear polarization (LP) is achieved, with a −10-dB IBW of 14.6% and a PG of 6.0 dBi at 7.7 GHz. When the access PIN diodes are activated, the antenna achieves left-handed CP (LHCP), exhibiting −10-dB IBW of 21.0%, a 3-dB ARBW of 18.4%, and a PG of 11.8 dBic at 6.9 GHz.
