    • A waveguide architecture for a dual-polarized antenna including multiple antenna elements. Aspects are directed to dual-polarized antenna architectures where each antenna element includes a polarizer having an individual waveguide with dual-polarization signal propagation and divided waveguides associated with each basis polarization. The waveguide architecture may include unit cells having corporate waveguide networks associated with each basis polarization connecting each divided waveguide of the polarizers of each antenna element in the unit cell with a respective common waveguide. The waveguide networks may have waveguide elements located within the unit-cell boundary with a small or minimized inter-element distance. Thus, unit cells may be positioned adjacent to each other in a waveguide device assembly for a dual-polarized antenna array without increased inter-element distance between antenna elements of adjacent unit cells. Antenna waveguide ports may be connected to unit cell common waveguides using elevation and azimuth waveguide networks of the corporate type.
    • 一种包括多个天线元件的双极化天线的波导结构。 方面涉及双极化天线结构,其中每个天线元件包括具有双极化信号传播的单独波导的偏振器和与每个基极化相关联的分束波导。 波导体系结构可以包括具有公司波导网络的单元电池,该单元电池与将基板单元中的每个天线元件的偏振器的每个分离的波导连接到相应的公共波导的每个基极化相关联。 波导网络可以具有位于单元单元边界内的波导元件,其具有小的或最小的元件间距离。 因此,单元电池可以在用于双极化天线阵列的波导器件组件中彼此相邻定位,而相邻单元电池的天线元件之间的元件间距离不会增加。 天线波导端口可以使用公司类型的仰角和方位波导网络连接到单元电池公共波导。
