    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.

    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： A receiver includes an array antenna, terminals, switches, a receiving circuit, a switch control unit and a reactance setting unit. Receiving circuit determines a received frequency and a received signal quality of a received signal by demodulating the received signal provided from the array antenna. The receiving circuit provides the received frequency to the reactance setting unit as a frequency setting signal, and provide the received signal quality to the switch control unit and the reactance setting unit. The reactance setting unit sets a set of the reactances corresponding to the received frequency in the terminals for each frequency, and the switch control unit switches connections in the switches to provide the received signal quality equal to or greater than the threshold.

    摘要： A switching circuit according to one embodiment is a switching circuit including at least one semiconductor switch element having an input, output, and a common terminals, a pulse-like signal being applied between the input and common terminals to switch a current between the output and common terminals. The switching circuit further includes a capacitance suppression element section connected at least one of between the input and output terminals, between the input terminal common terminals, and between the output and common terminals. The capacitance suppression element section reduces a parasitic capacitance between the terminals of the semiconductor switch element where the capacitance suppression element section is connected to less than that obtained when the capacitance suppression element section is not connected at a frequency N times (N is an integer of 1 or more) as high as a clock frequency of the pulse-like signal.
