Title:
SHIELD PLATE AND ELECTRONIC DEVICE
Document Type and Number:
Japanese Patent JP2020047730
Kind Code:
A
Abstract:
To provide a shield plate having a through-hole shaped to radiate noise dispersed in vertical polarization and horizontal polarization as compared with a simple circular or square through-hole, and an electronic device using the shield plate.SOLUTION: A shield plate includes a through-hole 5 having a point symmetric shape and penetrating the shield plate, and a pair of embedding portions 62 that form a part of an edge that extends inward from both sides so as to narrow the interval between the embedding portions and define the through-hole 5, and the through-hole 5 emits noise approaching circular polarization as compared with an original opening 6 when the embedding portion 62 is cut off by extrapolating the edge of a portion excluding a part formed by the embedded portion 62 among the edges defining the through opening 5.SELECTED DRAWING: Figure 2
