    • A flat antenna includes a 2×2 array of circular waveguide antenna elements that receive power from a splitting circuit including first to fourth striplines. The second stripline extends in two directions from one end of the first stripline. The third stripline extends in two directions from one end of the second stripline. The fourth stripline extends in two directions from the other end of the second stripline. Four feeder electrodes extend in mutually identical directions from the ends of the third and fourth striplines into the waveguides. The third and fourth striplines are bowed in way that shifts the second stripline closer to the center of the array. This arrangement permits a compact spacing of the waveguide antenna elements.
    • 扁平天线包括从包括第一至第四带状线的分离电路接收功率的圆形波导天线元件的2×2阵列。 第二带状线从第一带状线的一端向两个方向延伸。 第三带状线从第二带状线的一端沿两个方向延伸。 第四带状线从第二带状线的另一端向两个方向延伸。 四个馈电电极沿相互相同的方向从第三和第四带状线的端部延伸到波导中。 第三条和第四条带状线被鞠躬bow that,使第二条带线更接近阵列的中心。 这种布置允许波导天线元件的紧凑间隔。
