    摘要: In an antenna, a first element is connected to a GND of a feeder, on the same plane as a GND of a wireless circuit, and isolated from the GND of the wireless circuit. A second element is on the same plane as the GND of the wireless circuit and a first end connected to the first element and a second end as an open end. The third element has a first end connected to a power source of the feeder and located in a region occupied by the first element perpendicularly to the first element so that its first end source faces down. The fourth element has a first end connected to a second end of the third element and a second end as an open end, is parallel to the first element, and is perpendicular to a line connecting the first and second ends of the second element.

    摘要: An antenna device includes: a ground plate made of a conductor with a flat plate shape; an opposing conductive plate made of another conductor with a flat plate shape, arranged to space apart from the ground plate by a predetermined distance, and having a power supply point electrically connected to a power supply line; a short-circuit portion electrically connecting the opposing conductive plate and the ground plate; and a radio wave shield body for shielding a propagation of an electric field, which is arranged on an upper side of the opposing conductive plate and is made of a conductor or a dielectric material. Parallel resonance at a predetermined target frequency is generated by an inductance provided in the short-circuit portion and a capacitance between the ground plate and the opposing conductive plate.

    摘要: A transmission line assembly is configured such that (i) a first target inner layer is one of second to (N−1)-th pattern layers selected therefrom, and (ii) a second target inner layer is another one of the second to (N−1)-th pattern layers selected therefrom; the second to (N−1)-th pattern layers except for the first and second target inner layers are referred to as inner layers. The transmission line assembly includes band-like first and second slits formed through the ground pattern of a corresponding one of the first and second target inner layers to expose a part of one of dielectric layers; the one of the dielectric layers is adjacent to the corresponding one of the first and second target inner layers. Each of the first and second slits has an edge facing the interlayer line, and the edge of each of the first and second slits is concavely curved toward the interlayer line.

    摘要: A positioning system executes wireless communication with a portable terminal by adopting a radio wave of 1 GHz or higher to determine a position of the portable terminal relative to a vehicle. The positioning system includes a vehicle exterior communication device and a positioning device. The positioning device determines whether the portable terminal exists at an exterior operating area being a region outside a vehicle compartment within a predetermined operating distance from the vehicle, based on a reception status of the wireless signal received by the vehicle exterior communication device from the portable terminal in a first mode of the vehicle exterior communication device, and determines whether the portable terminal exists inside the vehicle compartment, based on the reception status of the wireless signal received by the vehicle exterior communication device from the portable terminal in a second mode of the vehicle exterior communication device.
