摘要

提出了一种覆盖ka波段卫星通信上行链路(27.5-31 GHz)的反射偏置馈电天线设计方案。该设计利用多模馈电喇叭天线与同轴腔相结合来产生所需的混合模式。这种馈电天线配置的主要优点是具有与偏置馈电天线相同的低交叉极化和副瓣电平。介绍了天线的设计细节，并与相同孔径的锥形喇叭天线的辐射方向图特性进行了比较。采用不同的分析方法，将该设计的最大孔径效率与多模开放式波导设计和锥形喇叭设计进行了比较，证明其孔径效率至少高出3%。

On the potential of using multimode reflectarray feeding horn antennas

A new design for a reflectarray offset feed antenna is presented to cover the ka band satellite communications uplink (27.5-31 GHz). The design exploits a multimode feed horn antenna combined with a coaxial cavity to produce the required mixture of modes. The main benefit of such a feed antenna configuration is the low cross polarization and sidelobe level as an offset feed antenna. The antenna design details are presented and the radiation pattern characteristics are compared to a conical horn antenna with the same aperture size. The maximum aperture efficiency of the proposed design is compared to the multimode open ended waveguide design as well as the conical horn using different analysis methods proving at least 3% higher aperture efficiency.
