Slot antenna and mobile terminal

Provided are a slot antenna and a mobile terminal, which relate to the technical field of antennas and are used for generating different resonance frequencies to cover a required frequency band. The slot antenna comprises: a system circuit board, a ground conductor, a radiator and a first adjustable unit, wherein the system circuit board is connected to the ground conductor to form an electrical conductor; the radiator is opposite to the electrical conductor to form a slot; a feeding end is provided 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, and the other end of the first adjustable unit is connected to the radiator; and the first adjustable unit is used for adjusting the resonance frequency of the slot antenna.
