    • A traveling-wave combining array antenna apparatus includes first and second traveling-wave array antennas. The first traveling-wave array antenna has a plurality of antenna elements provided at intervals along a first feeder line, and has a radiating directivity characteristic. The second traveling-wave array antenna has a plurality of antenna elements provided at intervals along a second feeder line, and has a main beam of a half-value width and a radiating directivity characteristic of a side lobe level lower than that of the first traveling-wave array antenna. A transmitting signal is split into two signals, feeding the signals to the first and second traveling-wave array antennas, which are provided so that a variation of main-beam radiating angle of electromagnetic wave of transmitting signal radiated from the first traveling-wave array antenna corresponding to a frequency change, and that of the second traveling-wave array antenna are substantially canceled by each other.
    • 行波组合阵列天线装置包括第一和第二行波阵列天线。 第一行波阵列天线具有沿着第一馈线设置间隔设置的多个天线元件,并具有辐射方向特性。 第二行波阵列天线具有沿着第二馈线设置间隔设置的多个天线元件,并且具有半波宽的主光束和比叶片的第一行进的低于其的旁瓣电平的散射方向特性 波阵列天线。 发送信号被分成两个信号,将信号馈送到第一和第二行波阵列天线,其被设置为使得从第一行波阵列辐射的发射信号的电磁波的主波束辐射角的变化 对应于频率变化的天线和第二行波阵列天线的天线基本上被彼此抵消。
