摘要：
A new method for the design of multilayer printed partially reflective surface (PRS) is proposed to achieve broadband, high efficiency, and miniaturization of Fabry-Perot resonant antenna (FPRA). In this letter, every two-layer structure is regarded as a resonator to obtain a narrowband positive reflection phase gradient and then cascaded to obtain a broadband. Finally, a three-layer PRS is designed and integrated to form a C-band compact FPRA with overall dimensions of 0.65 lambda(0)x0.65 lambda(0)x0.52 lambda(0) (lambda(0) is the free-space wavelength at the center frequency). The antenna was simulated, fabricated, and validated. The results show it has a high aperture efficiency due to the small aperture and a wide impedance bandwidth well covering 4.0-9.57 GHz.
