摘要： 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.

摘要： An antenna selection method includes selecting M1 antenna sets from CN−L1L2 antenna combinations, where L1 is a quantity of reserved antennas, a sum of L1 and L2 is equal to L, determining an antenna set with a maximum channel capacity, in M2 antenna sets, as a target antenna set to perform a preset-duration data transmission, where the M2 antenna sets are antenna sets formed by the M1 antenna sets and the L1 reserved antennas. The L1 reserved antennas include a maximum SNR in a target antenna set used in previous preset-duration data transmission. Each of the M2 antenna sets includes the L1 reserved antennas.

摘要： This application discloses a slot antenna and a terminal. The slot antenna includes a ground plane, an open slot disposed on the ground plane, a slot feeder, and a resonant circuit. The resonant circuit effectively excites a current on a surface of the ground plane, so that the ground plane becomes a primary radiator, and the antenna is a secondary radiator. Therefore, a volume of the antenna can be reduced without affecting radiation efficiency of the antenna.
