    Abstract: 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.

    Abstract: The present invention provides a method of producing a hardened aluminum alloy sheet having superior thermal stability, the method comprising the steps of: homogenizing an ingot of an aluminum alloy consisting essentially of, in weight percentage, 3.0 to 6.0% Mg and 0.4 to 0.8% Mn, with the balance being Al and incidental impurities; hot rolling the homogenized ingot to a sheet; cold rolling the hot-rolled sheet at a rolling reduction of at least 20%; intermediate heat treating the cold-rolled sheet at 200.degree. to 250.degree. C. for one hour or more; and final cold rolling the intermediate heat-treated sheet at a reduction of at least 50%. In this process, the aluminum ingot may further contain from 0.05 to 0.4% Cu with or without 0.05 to 0.5% Si, 0.1 to 0.5% Fe, 0.01 to 0.05% Ti and 0.0001 to 0.0010% B. Further, the above homogenizing and hot rolling steps may be replaced by the steps of homogenizing, hot rolling to a sheet thickness of 2 to 6 mm, cold rolling and annealing for recrystallization.
