Abstract: A cavity-backed slot antenna system provided in this disclosure is installed in a housing of an electronic device and includes a metal cavity, a supporting element, an antenna device, a conductive post, and a coupling metal part. The metal cavity is in the housing and includes an opening and a closed surface opposite to each other. A slot is on the closed surface. The supporting element is in the metal cavity. The antenna device is in the metal cavity and on the supporting element, to expose one side surface of the antenna device. The antenna device includes a feed source. The conductive post penetrates the antenna device and connects to the metal cavity. The coupling metal part is in the housing and close to the opening of the metal cavity, so that the coupling metal part is close to and corresponds to the feed source of the antenna device.
