    摘要: An array antenna apparatus includes a dielectric substrate, a feeder element, a parasitic element, and a directivity control unit. The feeder element and the parasitic element have an equal length. The feeder element and the parasitic element are arranged such that they intersect with each other at a substantially central portion of the parasitic element and a feeder unit of the feeder element and such that the parasitic elements are arranged symmetrically around the feeder element. An interval between the feeder element and the parasitic element is not larger than half wavelength of a radio wave. The parasitic element has a varactor diode serving as a variable capacitance element loaded. The directivity control unit supplies a control voltage to the varactor diode, and switches directivity of the array antenna apparatus.

    摘要: 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.
