    • An array antenna apparatus (100) includes a radiating element (A0) for receiving a transmitted radio signal, two parasitic elements (A1, A2), and two variable reactance elements (12-1, 12-2) connected to the respective parasitic elements (A1, A2), and a directivity characteristic of the array antenna apparatus is changed by changing reactances set to the variable reactance elements. An antenna controller (10) selects and sets one reactance to be set from those in a first case in which a first reactance set is set to the two variable reactance elements (12-1, 12-2) and a second case in which a second reactance set is set to the two variable reactance elements (12-1, 12-2) to be able to obtain a diversity gain equal to or larger than a predetermined value, based on a received radio signal, based on signal quality of the radio signal.
    • 阵列天线装置(100)包括用于接收发送的无线电信号的辐射元件(A 0),两个寄生元件(A 1,A 2)和两个连接到所述发射无线电信号的可变电抗元件(12-1,12-2) 相应的寄生元件(A 1,A 2)和阵列天线装置的方向特性通过改变设置到可变电抗元件的电抗而改变。 天线控制器(10)从将第一电抗设置为两个可变电抗元件(12-1,12-2)的第一种情况中选择并设置一个电抗,并且设置一个电抗 基于所接收的无线电信号,将第二电抗设置为两个可变电抗元件(12-1,12-2)以能够基于所接收的无线电信号的信号质量获得等于或大于预定值的分集增益 无线电信号。
