  • Patent number: 10340588
    Abstract: As such, in the disclosure, a slit is formed in a side plate. The slit has an opening in the upper end surface of the side plate. The opening has a width which is smaller than a thickness of the side plate and enables to correspond to a thickness t of the substrate and a length which enables to correspond to a length a of one side of the substrate. An RF antenna module is housed in the slit formed in the side plate of the housing to be accommodated in the housing by inserting the one side of the substrate through the opening of the slit, which is formed in the upper end surface of the side plate, and inserting the substrate into the slit by an amount equal to or larger than a length of another side of the substrate.

  • Publication number: 20190187515
    Abstract: According to the present invention, a display panel having a narrow frame and having an irregular shape is produced by a fewer number of steps, and the end faces of the polarizing plates are made flush with the end face of the glass substrate. Rectangular polarizing plates (51, 52) are bonded to a separate glass substrate (2) including a display region (21) with a cutout (31). The contour (41) of the separate glass substrate (2) and the contours (61) of the polarizing plates (51, 52) are simultaneously cut with use of an end mill or a laser.

  • Patent number: 9865928
    Abstract: In a multilayer substrate (2), an internal ground layer (11) is provided at a position between insulating layers (4) and (5) and a radiating element (13) is provided at a position between insulating layers (3) and (4). A first coplanar line (7) is connected to an intermediate position of the radiating element (13) in an X-axis direction, and a second coplanar line (9) is connected to an intermediate position of the radiating element (13) in a Y-axis direction. A passive element (16) is laminated on the upper surface of the radiating element (13) through the insulating layer (3). The passive element (16) is formed in a cross shape in which a first patch (16A) extending in the X-axis direction and a second patch (16B) extending in the Y-axis direction are orthogonal to each other.

  • Patent number: 9698487
    Abstract: In a multilayer substrate, eight front-side antenna portions and eight back-side antenna portions are disposed. Front-side radiation elements in the front-side antenna portions and back-side radiation elements in the back-side antenna portions are arranged in a staggered pattern when being vertically projected onto an back side of the multilayer substrate. The front-side radiation elements are disposed on a front side of the multilayer substrate, and a front-side ground layer is formed near the back side of the multilayer substrate. On the other hand, the back-side radiation elements are disposed on the back side of the multilayer substrate, and a back-side ground layer is formed near the front side of the multilayer substrate. The front-side radiation element and the back-side radiation element are disposed so as not to overlap each other when being vertically projected onto the back side of the multilayer substrate.

  • Patent number: 9660340
    Abstract: Two high frequency antennas are provided in a multilayer substrate. Each high frequency antenna is configured of a radiation element, a high frequency power supply line, and a high frequency power supply unit. A low frequency antenna is configured of a series radiation element, a low frequency power supply line, and a lower frequency power supply unit. The series radiation element is formed of two radiation elements connected by a radiation element connection line. One end side of the series radiation element is connected to the low frequency power supply unit via the low frequency power supply line. Open stubs to block transmission of a high frequency signal (SH) are connected to the radiation element connection line and the low frequency power supply line. Short stubs to block transmission of a low frequency signal (SL) are connected to the high frequency power supply lines.
