We propose a 1D beam steering high gain hybrid reflector-phased array antenna system for enhanced data rate wireless communication at Ku -band (12 - 14 GHz). The proposed hybrid antenna system consists of a ${D}$ = 50 cm offset parabolic-cylindrical reflector with ${f}/{D} = 0.4$ fed by an $8\times4$ dual linear-polarized stacked patch phased array antenna placed along the focal line of the reflector. The parabolic-cylindrical reflector has the property of a wide-angle beam steering along the cylindrical axis as compared to a conventional parabolic reflector. A complete implementation of the dual linear-polarized phased array antenna with the silicon RFIC chipset based beamforming network and integrated with aluminum offset parabolic-cylindrical reflector is reported. Cavity model and physical optics approximations are used to analyze the radiation characteristics of the phased array and the induced currents on the parabolic-cylindrical reflector surface, respectively. Furthermore, the multilevel fast multipole method (MLFMM) is used along with the method of moments (MoM) in TICRA GRASP for a comprehensive analysis of the proposed hybrid reflector system. The peak directivity of the reflector pattern is around 27 dBi for both the X-polarization and Y-polarization, and a beam scanning of ±30° is achieved along the cylindrical axis of the reflector for 3 dB reduction in the gain. The analytical and computed results of the proposed hybrid reflector-phased array antenna system are experimentally verified.

我们提出了一种一维波束控制高增益混合反射器相控阵天线系统，用于增强数据速率下的无线通信。 苦 频段（12-14 GHz）。拟议的混合天线系统包括一个 $ {D} $ = 50厘米偏移抛物柱面反射镜，具有 $ {f} / {D} = 0.4 $ 由一个 $ 8 \ times4 $ 沿反射镜焦线放置的双线性极化堆叠式贴片相控阵天线。与传统的抛物面反射器相比，抛物柱面反射器具有沿圆柱轴方向转向的广角光束的特性。报告了具有基于硅RFIC芯片组的波束形成网络并与铝偏置抛物柱面反射器集成的双线性极化相控阵天线的完整实现。腔模型和物理光学近似分别用于分析相控阵的辐射特性和抛物柱面反射镜表面的感应电流。此外，TICRA GRASP中使用了多级快速多极方法（MLFMM）和矩量方法（MoM）来对所提出的混合反射器系统进行全面分析。对于X偏振和Y偏振，反射器图案的峰值方向性都约为27 dBi，并且沿着反射器的圆柱轴实现了±30°的光束扫描，从而使增益降低了3 dB。实验验证了所提出的混合反射器相控阵天线系统的分析和计算结果。
