Abstract: Embodiments of the present disclosure provide a multi-band antenna and a terminal device. The multi-band antenna includes a feedpoint, a matching network, a capacitor assembly, a radiation portion, and a grounding portion. The feedpoint, the matching network, the capacitor assembly, the radiation portion, and the grounding portion are connected in sequence. The matching network includes at least a serially-connected inductor and a grounded capacitor or inductor. The grounding portion is electrically connected to a ground plane. A first resonant circuit is formed from the feedpoint to the grounding portion. The first resonant circuit generates a first resonance frequency and a second resonance frequency. The first resonance frequency is used in a CRLH mode, and the second resonance frequency is used in a half-wavelength loop mode.

Abstract: A mobile communications terminal includes a metal backplane, a circuit board, and a metal frame. A feeding structure is located between a first ground point and a second ground point. A slot is located between the first ground point and the feeding structure. The first antenna uses, as a radiator, a part of the metal frame between the slot and the first ground point. The second antenna uses, as a radiation slot, a gap between the metal backplane and the part of the metal frame between the slot and the first ground point. The third antenna uses, as another radiation slot, a gap between the metal backplane and a part of the metal frame between the slot and the second ground point.

Abstract: A communications terminal includes an antenna structure and a metallic frame that includes at least one slot. The antenna structure includes an NFC antenna and a non-NFC antenna. The NFC antenna includes an NFC radiator, a first filtering unit, and an NFC circuit, and the non-NFC antenna includes a non-NFC radiator, a second filtering unit, and a non-NFC circuit. The NFC radiator and the non-NFC radiator are formed by the metallic frame of the communications terminal, and the entire non-NFC radiator is in the NFC radiator. The NFC circuit is coupled to the NFC radiator by using the first filtering unit, the non-NFC circuit is coupled to the non-NFC radiator by using the second filtering unit, the first filtering unit is configured to filter out a non-NFC signal, and the second filtering unit is configured to filter out an NFC signal.
