  • Patent number: 11387557
    Abstract: The invention provides an antenna for multi-broadband and multi-polarization communication, which may include a plurality of radiators configured to jointly function as one or more dipoles, and a plurality of parasitic elements. Each radiator may be configured to contribute to resonances at two or more nonoverlapping bands, and may comprise an arm and a ground wall connecting the arm and a ground plane. The arm may comprise an arm plate and a folded arm. The ground wall may comprise a meandering portion causing a distance between the arm and the ground plane to be shorter than a length of a current conduction path along the ground wall between the arm and the ground plane. On a geometric reference surface, a projection of each parasitic element may extend between two gaps which clamp a projection of an associated one of the radiators.

  • Publication number: 20110143872
    Abstract: An electronic control V-belt continuously variable transmission mechanism is applied in a power transmission system having an engine and support shafts for a driving pulley and a driven pulley, characterized by driving the driving pulley with power supplied by a pulley driving system such that a movable portion of the driving pulley moves axially to the driving-pulley support shaft, thereby enabling a movable portion of a driven pulley connected to the driving pulley to move in response to the axial distance variation, thus changing the rotational speed of the driven pulley. The contact between a cam guide groove of a bearing base of the pulley driving system and a cam guide device is transmitted through rolling friction, and the transmission efficiency is increased by a complex lead angle effect formed between a lead angle of the cam guide groove and a lead screw.
