  • Patent number: 11888227
    Abstract: An antenna device is supported by a supporting member. The antenna device includes a dielectric substrate and a patch antenna. The patch antenna comprises a radiating element and a ground conductor that are provided to the dielectric substrate. The linear conductor fixes a relative position between the antenna device and the supporting member in a direction orthogonal to a normal direction of the dielectric substrate. At least a part of the linear conductor is electromagnetically coupled with the patch antenna to act as a linear antenna.

  • Publication number: 20210399437
    Abstract: An antenna device includes a dielectric substrate and a plurality of radiating elements that each have a flat profile. A groove, continuous or segmented, is formed in the dielectric substrate to surround the radiating element in plan view. Another groove, continuous or segmented, is formed around another radiating element. The radiating element and the another radiating element are adjacent to one another.

  • Publication number: 20170033445
    Abstract: In the present invention, a metallic section (22) has an opening (21). An antenna 6 is provided in a terminal device 1, in a location overlapped with the opening 21 when the opening (21) is viewed from an opening surface of the opening (21). The metallic section (22) has the opening (21) such that the metallic section (22) includes a notch-like shape when the opening (21) is viewed from the opening surface, the notch-like shape being cut out from a side of the metallic section which side is closer to the antenna (6). This ensures body rigidity while also enabling the antenna to exhibit favorable properties during use of the terminal device (1) by a user.

  • Patent number: 9262314
    Abstract: A data transfer device includes a FIFO memory and a control unit which obtains a data amount of the FIFO memory to control the FIFO memory and outputs a selection signal corresponding to the obtained data amount of the FIFO memory. An output data generation unit generates output data including either one of the second output data and an interpolation data selected based on the selection signal, and a first output data stored in a frame memory.

  • Publication number: 20110148719
    Abstract: A mobile phone terminal (portable wireless device) of the present invention includes: a first housing; a slide plate fixed to the first housing; a second housing slidably attached to the slide plate; and an antenna attached to the first housing. The slide plate is constituted by a conductive part made from a metal and a nonconductive part made from an insulating material. The nonconductive part is provided so as to extend across the slide plate. According to the arrangement, it is possible to suppress a reduction in gain of the antenna, which reduction is generated due to a resonance current flowing through the slide plate in the portable wireless device.

  • Patent number: 7966050
    Abstract: In a portable communication terminal capable of assuming a state where a first casing 1 and a second casing 2 connected rotatably overlap substantially and a state where they are rotated relative to each other by 90° from the former state, the second casing 2 including a display unit 3 is rotated by about 90°, so that the display unit 3 is made horizontally long, thus enabling the displaying with good visibility. At the same time, the rotation causes the first casing 1 at an upper edge thereof not to overlap with the second casing 2, and an antenna 5 is disposed at the not-overlapping portion, thus increasing an electrical volume of the antenna to provide broad-band and good antenna characteristics. Since the antenna 5 overlaps with the second casing 2 when in normal use, the antenna does not protrude, thus keeping the terminal compact and slim to provide excellent portability.

  • Publication number: 20090176541
    Abstract: In a mobile wireless terminal device comprising a first housing that contains a first substrate; an antenna that is disposed in an upper edge portion of the first housing; and a second housing that is disposed in the upper edge portion of the first housing in an openable/closeable manner through a hinge portion, and that contains a second substrate, characterized in that the first substrate and the second substrate are connected by a cable including a GND and a signal line, and current distribution control means having a frequency characteristic with a predetermined impedance is disposed at an arbitrary position on the cable, the cable and a GND on the substrate are connected at an optimum position in each frequency band, and thereby it is possible to obtain excellent antenna characteristics in all frequency bands in use, regardless of a position of a cable connector.
