Abstract

The invention discloses an integrated AIP assembly, a terminal device and a terminal device shell, the integrated AIP assembly comprises metamaterial structures and an AIP assembly body, and the metamaterial structures are arranged above the AIP assembly body at intervals; the metamaterial structures adopt a metal structure layer, and the metal structure layer is arranged on the surface of the device shell and is arranged close to one side of the AIP assembly body; the equivalent dielectric constant of the device shell provided with the metal structure layer is matched with the dielectric constant of vacuum; the metamaterial structures are arranged above the AIP assembly body at intervals, the electromagnetic metamaterial theory is utilized, the equivalent dielectric constant of the deviceshell is reduced, it is ensured that the performance of the AIP assembly body in the device equipment is close to the performance of the AIP assembly body in a free space, and the effects of performance compensation of the AIP assembly body and approximate transparency of antenna radiation are achieved; the matching performance of the antenna in a working frequency band and the normal gain of theantenna in a free space are effectively recovered, the scanning angle of the antenna is improved, the universality of the integrated AIP assembly is effectively improved, and the design and manufacturing process is simple.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and in particular relates to an integrated AIP component, a terminal device and a shell of the terminal device. Background technique [0002] In 5G terminal equipment, millimeter-wave antennas have become a significant development trend; and because in millimeter-wave frequency bands, antennas need to use high gain and adjustable beams to resist greater propagation loss compared with sub-6GHz frequency bands, millimeter-wave The wave antenna must be designed in the form of an active array; considering the precision control and cost requirements of mass production, it is currently a popular solution to use common integrated AIP (Antenna-in-Package) components in different types of terminal equipment. [0003] Due to the needs of terminal industrial design, the materials of the equipment shells in different types of terminal equipment are very different, such as glass, ceramics and e...
