    摘要: In an antenna device, first and second vertically-polarized antennas are disposed at respective horizontal end portions of a substrate. A first ground pattern functioning as a ground plane of the first antenna and a second ground pattern function as a ground plane of the second antenna are disposed on the substrate. An intermediate pattern is located between the first ground pattern and the second ground pattern and functions as a horizontally-polarized non-feed element for the first antenna and the second antenna. The phase control part controls a phase difference between a signal of the first antenna and a signal of the second antenna by changing at least one of a phase of the signal of the first antenna and a phase of the signal of the second antenna. The combining portion combines the signals after the phase control part controls the phase deference.

    摘要: A power supply apparatus for a vehicle supplies/charges electric power to/from a power supply unit. The vehicle includes a first power-inverter circuit, a capacitor, high-resistance and low-resistance electric-paths between the capacitor and a battery, a first switching unit opening/closing the electric-paths, and a unit operating the first switching unit, when connecting between the battery and the first power-inverter circuit, in such a manner that after the high-resistance electric path is closed and the low-resistance electric path is opened, the high-resistance electric-path is opened and the low-resistance electric-path is closed. The apparatus includes an electric power transferring electric-path, an operating unit operating the first power-inverter circuit to supply/receive electric power to/from the power supply unit, and a prohibiting unit prohibiting the electric-path between the power supply unit and the first power-inverter circuit from closing when the amount of charge of the capacitor is equal to or less than a predetermined value.

    摘要: An antenna apparatus has a ground plane and a traveling-wave linear antenna The ground plane has a dielectric layer and metallic plates disposed on the dielectric layer. The plates placed on a front side of the ground plane act as a band gap surface. The dielectric constant and thickness of the dielectric layer, the number of plates and the width of spaces among the plates are adjusted, so that the band gap surface prevents propagation of electromagnetic waves within a specific frequency band. The antenna is disposed over the band gap surface on the front side of the ground plane to be spaced away from the band gap surface. The antenna radiates electromagnetic waves of an operational frequency within the specific frequency band in response to an alternating current of the operational frequency fed to the linear antenna.

    摘要: An antenna apparatus is disclosed. The antenna apparatus includes a board and a line antenna. The board includes: a base part having dielectric layers and a conductive layer disposed between the dielectric layers; multiple metal plates arranged on one surface of the base part while being spaced apart at even intervals so as to provide a band-gap surface; and a connection part via which the conductive layer is electrically connectable with the multiple metal plates. The line antenna is located on a band-gap surface side of the board, is arranged along the band gap surface, and is configured to receive and transmit the electromagnetic wave within an operating frequency band. The connection part includes a first adjustment circuit that is configured to individually adjust an impedance between the conductive layer and each of the plurality of metal plates.
