Abstract: An electronic device includes a radiator, a first feed circuit, and a second feed circuit. The radiator includes a first branch. The first feed circuit feeds the radiator at a first end of the first branch, and the second feed circuit feeds the radiator at a first position in the first branch. The first position is in an area with a largest current in the first branch when the first feed circuit performs feeding and the second feed circuit does not perform feeding.

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.
