Abstract
The present invention relates to a composite laminate plate, a housing and a mobile communication device. The composite laminate includes a top metal layer with a through hole and an array antenna, and an area ratio of the array antenna to the through hole meets a specific range, thereby enhancing wave transmissivity of a millimeter wave. Moreover, the composite laminate has a specific material structure, such that it has good mechanical properties and low density. The housing and the mobile communication device made by the composite laminate have advantages of metallic texture, high signal intensity and excellent effect for light weight tendency.
Claims14
A composite laminate plate, comprising:
- a top metal layer, having a first through hole;
- a first fiber-reinforced resin layer, having two opposite sides, wherein one of the two opposite sides is adjacent to the top metal layer;
- a functional layer, adjacent to an other of the two opposite sides of the first fiber-reinforced resin layer, wherein the functional layer has a groove;
- an array antenna, disposed in the groove, wherein the first through hole is disposed corresponding to the array antenna;
- and
- a bottom-layer structure, adjacent to the functional layer and disposed on an other side of the functional layer opposite to the first fiber-reinforced resin layer, wherein the bottom-layer structure comprises a bottom metal layer disposed under the functional layer;
- and based on an area of the array antenna being 100%, an area of the first through hole relative to the array antenna is 10% to 80%.
