An acquisition apparatus for acquiring the positional information indicating the position of a position detecting device which, in one embodiment, detects position based on a GPS (Global Positioning System). The position detecting device measures the device distance to each of a plurality of satellites and calculates the device position based on the device distance and the position of each of the plurality of satellites. The acquisition apparatus comprises a receiving part for receiving the device distance and the device position from the position detecting device, and a verification position calculating part for calculating the verification position that is the position to be calculated by the position detecting device, based on the received device distance and the position of each of the plurality of satellites at the time of measuring the device distance. The apparatus further includes a validity judgment part for judging that the device position detected by the position detecting device is valid, on condition that the device position is coincident with the verification position.

An antenna consisting of a single small and lightweight package, where each radiating element operates independently with reduced interference among the radiating elements. An integrated multi-element planar antenna includes a ground patternwith a notchformed at an end, first radiating elementplaced on one side of the notchand equipped with a feeder, and second radiating elementplaced on the other side of the notchand equipped with a feeder. For example, inverted F antennas are used as the first radiating elementand second radiating element. The first radiating elementand second radiating elementare placed symmetrically about the notchsuch that separation distance will be the largest at locations where their radiation fields are the highest.

Planar antenna with multiple radiators and notched ground pattern

Antenna devices are provided comprising antenna structures encapsulated or molded into plastic covers of computing devices to enable wireless communication. For example, one or more antenna structures can be encasulated within, or molded into, a plastic display cover of a portable laptop computer. Embedded antenna designs can include various antenna types that are built using one or more wires or thin metallic strips encapsulated into plastic device covers. Insert/injection molding methods can be used to encapsulate antenna structures in plastic device covers during fabrication of the plastic device covers.

An aperture antenna is provided so that it is capable of matching with a standardized coaxial cable without employing any matching circuit. The aperture antenna includes a first flat electric conductor with an aperture in which a second aperture length in a second direction perpendicular to a first direction is greater than a first aperture length in the first direction. A second electric conductor, spaced from the first electric conductor is disposed inside the aperture in practically the same plane with the first electric conductor. Further included is a non-balance type transmission line.

Antenna and information processors

A portable device having a base member and a hingedly attached lid member does not require a signal cable to transmit a high-frequency signal between the base unit and the lid. While the lid of the lap-top PC is closed, a radio device installed in the base unit transmits a high-frequency signal from a first antenna to a second antenna, the signal is then output from a signal cable attached third antenna to the atmosphere. The device structured as described above can transmit the high-frequency signal in a non-contact manner between the antenna of the base unit and the antenna of the lid in such a way that there is no need to provide a signal cable between the base unit part and the lid part.
