Small-aperture and low sidelobe level Fabry-Perot resonator antenna

A high-performance and low sidelobe level (SLL) Fabry-Perot resonator antenna (FPRA) shielded by perfect electric conductor (PEC) and artificial magnetic conductor (AMC) is proposed. The aperture size of the antenna is about 1.45 \lambda * 1.45 \lambda and the aperture efciency is 89%. Meanwhile, th...

More Information
Summary:A high-performance and low sidelobe level (SLL) Fabry-Perot resonator antenna (FPRA) shielded by perfect electric conductor (PEC) and artificial magnetic conductor (AMC) is proposed. The aperture size of the antenna is about 1.45 \lambda * 1.45 \lambda and the aperture efciency is 89%. Meanwhile, the features including more than 5.7% (3dB gain drop) bandwidth and lower than -15dB sidelobe level make it more superior than conventional horn antennas in satellite communications.
