  • Publication number: 20240347906
    Abstract: The present invention relates to a full analog phase shifter and an antenna apparatus including same, and more particularly, comprises: a variable switch panel including a first conductive pattern terminal and a second conductive pattern terminal; and an antenna element substrate on which a plurality of array antenna elements are arranged and a transmission line being in contact with the first conductive pattern terminal and the second conductive pattern terminal is pattern-printed, wherein, due to a phase shift caused by contact points of the transmission line with respect to the first conductive pattern terminal and the second conductive pattern terminal, phases of the plurality of antenna elements are linearly array distributed on a same reference phase plane, thereby providing an advantage of easily implementing a mirror symmetry structure having a linear phase distribution only by a phase shift in an RF stage without phase conversion in a digital stage.

  • Publication number: 20240300432
    Abstract: An airbag chute-integrated crash pad assembly includes: a main core that includes a door portion expanding when an airbag expands, and a cover portion mounted on a dash board. In particular, the main core is formed with a reinforcement portion extending downward from a lower surface of the cover portion, and the door portion and the cover portion are separated by a hinge groove that is formed in a lower surface of the main core and forms an expansion line. The reinforcement portion is combined with an airbag accommodation body that accommodates a passenger airbag (PAB). Thus, process optimization can be realized by omitting a process of machining a score and fusing a PAB chute, and also a problem of damage to the PAB chute can be solved.
