Metal back-cavity antenna device

Abstract

The disclosure provides a metal back-cavity antenna device, which is installed on a metal case. The metal back-cavity antenna device includes a ground metal plate, a metal radiation cover, a metal connecting side plate and an antenna module. In the metal cavity-backed antenna device, the ground metal plate is disposed on the metal case and contacts the metal case. The metal radiation cover is located above the ground metal plate, and a slot is provided on the metal radiation cover. The metal connecting side plate connects one long side of the ground metal plate and a first long side on the same side of the metal radiation cover, so that the ground metal plate, the metal connecting side plate and the metal radiation cover jointly form a metal cavity. The antenna module is located in the metal cavity and installed on the metal radiation cover.
