Metal back-cavity antenna device

Abstract

The disclosure provides a metal back-cavity antenna device arranged on a metal case, which includes a ground metal plate, a metal radiation cover plate, a metal connecting side plate, and an antenna module. In the metal back-cavity antenna device, the ground metal plate is arranged on the metal case and in contact with the metal case. The metal radiation cover plate is located on the ground metal plate, and a slot is provided on the metal radiation cover. The metal connecting side plate is connected to a long side of the ground metal plate and a first long side of the metal radiation cover plate on a same side, so that the ground metal plate, the metal connecting side plate, and the metal radiation cover plate jointly form a metal cavity. The antenna module is located in the metal cavity and mounted on the metal radiation cover plate.
