摘要： Embodiments of the present invention provide a multi-band antenna and a terminal device. The multi-band antenna includes: a feeding part is connected to a capacitor component to form a feeding circuit, and a feeding matching circuit is electrically connected between a feeding radio frequency circuit and the feeding circuit; a radiation part is electrically connected both to the feeding circuit and a grounding part; the grounding part is electrically connected to a ground plane; a first resonant circuit is formed from the feeding circuit to an end that is of the radiation part and that is away from the grounding part; and the first resonant circuit generates a first resonance frequency and a second resonance frequency.

摘要： The present invention relates to the field of antenna technologies, and provides 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.
