ANTENNA MODULE

TWN11081420312021217342021/06/01一種天線模組，包含天線與週期性結構。週期性結構設置於天線的一側，包含多個第一柱體、多個第一橋件及多個第二柱體。週期性結構的多個第一柱體沿一維陣列間隔地排列。週期性結構的多個第一橋件沿一維陣列間隔地排列，且連接前述多個第一柱體遠離天線的一側，其中多個第一橋件定義第二虛擬層。週期性結構的多個第二柱體平行第一柱體間隔地排列且連接前述多個第一橋件遠離天線的一側。各第二柱體與相鄰的各第一柱體於垂直第二虛擬層的方向相互錯位。使週期性結構產生可反射電磁波的效果，使得天線模組輻射效率提升。 An antenna module includes an antenna and a periodic structure. The periodic structure is disposed on one side of the antenna, and includes a plurality of first pillars, a plurality of first bridge members, and a plurality of second pillars. The plurality of first pillars of a periodic structure are arranged at intervals along a one-dimensional array The plurality of first bridge members are arranged at intervals in an arrangement direction, and connect the side of the plurality of first pillars away from the antenna, wherein the plurality of first bridge members define a second virtual layer. The plurality of second pillars are arranged in parallel with the first pillars and are connected to a side of the plurality of bridge members away from the antenna. Each of the second pillars and the first pillars adjacent to the second pillars are offset from each other in the direction perpendicular to the second virtual layer. The periodic structure has an effect of reflecting electromagnetic waves, so that the radiation efficiency of the antenna module could be improved.補正完
