    • A circularly polarized waveguide slot array includes first and second waveguide sections, the first waveguide section extending along a longitudinal axis, and including an antenna element for transmitting or receiving a circularly polarized signal. The second waveguide slot section is coupled side-to-side with the first waveguide slot section and extends along the longitudinal axis, the second waveguide slot section including an antenna element for transmitting or receiving the circularly polarized signal at a phase which is substantially complementary to the circularly polarized signal transmitted by or received by the first waveguide slot section. Further exemplary, the antenna element disposed on the first waveguide slot section is offset from said antenna element disposed on the second waveguide slot section substantially one half of a predefined guide wavelength λg along said longitudinal axis.
    • 圆偏振波导狭缝阵列包括第一和第二波导部分,第一波导部分沿着纵轴延伸,并且包括用于发送或接收圆偏振信号的天线元件。 第二波导槽部分与第一波导狭槽部分一侧并排连接并沿着纵向轴线延伸,第二波导槽部分包括天线元件,用于以与第一波导槽部分基本互补的相位发送或接收圆偏振信号 由第一波导槽部分发送或接收的圆偏振信号。 进一步示例,设置在第一波导槽部分上的天线元件从布置在第二波导槽部分上的所述天线元件基本上沿着所述纵向轴线预定导向波长»g的一半偏移。
