Title:
LARGE-SCALE ARRAY ANTENNA AND ANTENNA MODULE
Document Type and Number:
WIPO Patent Application WO/2021/135274
Kind Code:
A1
Abstract:
The present invention relates to an antenna module and a large-scale array antenna. The antenna module comprises a metal reflecting plate, a first insulator, a second insulator, a feed power division network, and a calibration network. The metal reflecting plate is embedded between the first insulator and the second insulator, and the metal reflecting plate, the first insulator, and the second insulator are integrally molded. The first insulator comprises an insulating bottom plate located on one side surface of the metal reflecting plate, and the feed power division network is arranged on the insulating bottom plate. The second insulator comprises an insulating cavity located on the other side surface of the metal reflecting plate, and the calibration network is arranged on the bottom wall of the insulating cavity. The metal reflecting plate, the first insulator, and the second insulator are integrally molded, and then the feed power division network is directly arranged on the insulating bottom plate and the calibration network is directly arranged on the bottom wall of the insulating cavity, so that a lightweight antenna can be implemented, the structure of the antenna is simplified, the performance index of the antenna is improved, the assembly is simplified, and automatic production is facilitated.
