    • A mobile communication base station antenna has two array antennas juxtaposed in a horizontal direction. Each of the array antennas includes a plurality of antenna element pairs arranged in a vertical direction. Each of the antenna element pairs includes two antenna elements having polarization characteristics perpendicular to each other. A shield plate is provided between the two array antennas. The plurality of antenna element pairs of each of the two array antennas are classified into a first group of M-antenna element pairs, a second group of N-antenna element pairs, and a third group of P-antenna element pairs from one end to another end of the two array antennas (M, N, and P are positive integers, respectively). The electric power is fed from one feeding point to the antenna elements of the first and third group of one of the two array antennas and the antenna elements of the second group of another of the two array antennas, and a tilt angle of the two array antennas with respect to a horizontal plane is set to be a predetermined tilt angle by electrical tilting.
    • 移动通信基站天线具有在水平方向上并列的两个阵列天线。 每个阵列天线包括沿垂直方向布置的多个天线元件对。 每个天线元件对包括具有彼此垂直的偏振特性的两个天线元件。 在两个阵列天线之间设置屏蔽板。 两个阵列天线中的每一个的多个天线元件对被分为第一组M天线元件对,第二组N天线元件对和第三组P天线元件对,从一端到 两个阵列天线的另一端(M,N和P分别为正整数)。 电力从一个馈电点馈送到两个阵列天线之一的第一和第三组的天线元件以及两个阵列天线中另一组的第二组的天线元件,并且两个阵列的倾斜角 相对于水平面的天线通过电倾斜被设定为预定的倾斜角。
