Abstract: 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.

Abstract: 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.
