Abstract: An antenna apparatus includes a feeding antenna inside an electronic device and one or more antenna elements, such as a floating metal antenna, disposed on a rear cover of the electronic device. The floating metal antenna and a feeding antenna inside the electronic device may form a coupling antenna structure. The feeding antenna may be an antenna fastened on an antenna support (which may be referred to as a support antenna). The feeding antenna may alternatively be a slot antenna formed by slitting on a metal middle frame of the electronic device. The antenna apparatus may be implemented in limited design space, thereby effectively saving antenna design space inside the electronic device. The antenna apparatus may generate excitation of a plurality of resonance modes, so that antenna bandwidth and radiation characteristics can be improved.

Abstract: Embodiments of the present invention relate to the field of antenna technologies, and provide a slot antenna and a mobile terminal, to generate different resonance frequencies, so as to cover required bands. The slot antenna includes a system circuit board, a grounding conductor, a radiator, and a first adjustable unit. The system circuit board is connected to the grounding conductor to form an electric conductor, and the radiator is opposite to the electric conductor to form a slot. A feeding end is disposed on the system circuit board, the feeding end is electrically connected to the radiator, one end of the first adjustable unit is connected to the system circuit board, the other end of the first adjustable unit is connected to the radiator, and the first adjustable unit is configured to adjust a resonance frequency of the slot antenna.
