    摘要: A satellite antenna positioner having a predictive maintenance function, according to an embodiment of the present inventive concept, relates to a satellite antenna positioner having a predictive maintenance function, which supports an antenna and is configured to orient the antenna on the basis of a received satellite signal, the satellite antenna positioner comprising: a first motor which generates driving power for adjusting the elevation of the antenna; a first gear which rotates the antenna about a first axis while reducing the rotation speed of the first motor; a second motor which generates driving power for adjusting the azimuth of the antenna; a second gear which rotates the antenna about a second axis perpendicular to the first axis while reducing the rotation speed of the second motor; a control module which controls the first motor and the second motor on the basis of the sensitivity of the received satellite signal; and a predictive maintenance module which monitors whether at least one of the first gear and the second gear is abnormal.

    摘要: An ultra-wideband monopole antenna for 5G application is disclosed comprising a first quarter wavelength conductor and a second quarter wavelength conductor, for transmitting and/or receiving electromagnetic waves. A flat portion of the first quarter wavelength conductor and a flat portion of the second quarter wavelength conductor are preferably arranged and located perpendicular and intersecting to each other. Two curved wings of the first quarter wavelength conductor and two curved wings of the second quarter wavelength conductor are preferably arranged and located concentrically and having a same center. The first and second quarter wavelength conductors are joined to deliver ultra wideband frequency in the range of 600-960 MHz and 1710-6000 MHz.

    摘要: A glazing unit extends along a plane, P, defined by a longitudinal axis, X, and a vertical axis, Z; having a width, W, measured along the longitudinal axis, X, and a length, L, measured along the vertical axis, Z, and includes at least a glass panel and an antenna unit. The antenna unit includes an antenna. The antenna unit also includes a fixing portion for fixing the antenna to the glass panel so that a space, S, through which air can flow is formed between the glass panel and the antenna. At least one non-fixing portion and at least one metallic element are placed over at least a part of the non-fixing portion of the antenna unit.

    摘要: A radio frequency and electromagnetic emission shield employed on wireless personal and portable electronic devices, containing one or more layers of radio frequency (RF) or electromagnetic (EM) screening material, shielding the user from harmful RF or EM radiation, or a redirection antenna that receives all RF signals, and redirects those signals away from the user. The RF emission shield may be contained within a plurality of outer layers, providing a secure fit to a wireless electronic device and an outer layer providing an easy grip for the user.

    摘要: The present invention relates to a clamping apparatus for an antenna, the clamping apparatus including a rotation unit configured to rotate an antenna in a horizontal direction, a tilting unit configured to rotate the antenna in a vertical direction, and a rotation/vibration prevention unit configured to adjust a direction of the antenna by rotating at least one of the rotation unit and the tilting unit and prevent the antenna from arbitrarily rotating after the direction of the antenna is adjusted, in which the rotation/vibration prevention unit includes a rotation motor, a worm gear configured to be rotated by the rotation motor, a shaft configured to define at least one rotation center, and a worm wheel gear installed on an outer peripheral surface of the shaft and configured to rotate at least one of the rotation unit and the tilting unit while being rotated by the worm gear, thereby easily adjusting the direction of the antenna by controlling the rotation motor and preventing the antenna with the adjusted direction from arbitrarily rotating.

    摘要: A radar level gauge system include a transceiver; an antenna; a hollow waveguide for guiding the transmit signal from a first end facing the transceiver towards a second end facing the antenna; a housing including a heat-dissipating structure arranged at a first distance from the second end; a first thermal connection between the hollow waveguide and the heat-dissipating structure; and a second thermal connection between the hollow waveguide and the housing arranged at a second distance, shorter than the first distance, from the second end. The first and second thermal connection are arranged such that a thermal resistance of a first heat conduction path from the second end of the hollow waveguide through the first thermal connection to the heat-dissipating structure, is lower than a thermal resistance of a second heat conduction path from the second end of the hollow waveguide through the second thermal connection to the housing.
