基于射线跟踪模型, 提出了一种超材料角反射面结构, 实现了Fabry-Perot天线增益和口径效率的提升. 首先对基于超材料角反射面的Fabry-Perot天线进行了理论推导和分析. 然后, 设计并分析了双圆极化馈源、基于超材料角反射面的Fabry-Perot天线及其性能. 最后, 对所提出的Fabry-Perot天线模型进行了制造和测试. 结果表明, 该天线的左圆极化增益和右圆极化增益分别为21.4 dBi和21.3 dBi. 相比馈源天线, 增益分别提高了16.4 dB和16.3 dB. 与传统Fabry-Perot天线相比, 所提出超材料角反射面同时充当了反射面和相位校正面, 实现了对Fabry-Perot天线边缘电磁波的有效调控. 所设计Fabry-Perot天线工作在2.8 GHz频段, 具有高增益、高口径效率和低旁瓣的优点, 满足了太阳射电望远镜F107指数观测的需求.

Based on the ray-tracing model, a new method of achieving a high gain and high aperture efficiency Fabry-Perot antenna with metamaterial-based corner reflector is proposed. The proposed Fabry-Perot antenna is composed of a dual circularly polarized patch antenna feed and the metamaterial-based corner reflector. The metamaterial-based corner reflector consists of four phase correction metasurfaces and a partially reflective surface. First, theory and analysis of the Fabry-Perot antenna with metamaterial-based corner reflector are presented. Then, the performances of the dual circularly polarized antenna feed, the traditional Fabry-Perot antenna, and the Fabry-Perot antenna with metamaterial-based corner reflector are compared among each other and analyzed. Finally, the proposed Fabry-Perot antenna is fabricated and measured. The measured left-hand circular polarization (LHCP) gain and the measured right-hand circular polarization (RHCP) gain of the proposed Fabry-Perot antenna are 21.4 dBi and 21.3 dBi, respectively. Comparing with the antenna feed, the LHCP gain and RHCP gain of the proposed Fabry-Perot antenna are enhanced by 16.4 dB and 16.3 dB, respectively. Compared with the traditional Fabry-Perot antenna, the metamaterial-based corner reflector acts as both a reflection surface and a phase correction surface. It manipulates the propagation direction and phase of electromagnetic wave. The proposed Fabry-Perot antenna with high gain, high aperture efficiency and low sidelobe at 2.8 GHz paves the way for developing the solar radio telescope and conducting the observation.-
