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.

Abstract: A proximity sensor and a mobile communication device thereof are provided. The mobile communication device includes an antenna structure, a matching circuit, a capacitance sensing circuit and a processing circuit. The matching circuit couples to the antenna structure. The capacitance sensing circuit couples to the matching circuit. The capacitance sensing circuit senses a capacitance variation on the antenna structure via the matching circuit and accordingly generates a proximity sensing signal. The processing circuit is coupled to the capacitance sensing circuit to receive the proximity sensing signal. When a signal level of the proximity sensing signal exceeds a first threshold value, an object is determined approaching, and when the signal level of the proximity sensing signal exceeds a second threshold value, a human body is determines approaching. The first and the second threshold value are different.
