Abstract: A mobile terminal and an antenna that includes a feeder and a radiating element. The radiating element includes a first radiating patch and a second radiating patch. The first radiating patch and the second radiating patch are located on one side of the feeder and form a loop together with the feeder. An adjustable component configured to control the feeder and the second radiating patch is disposed on the feeder between the first radiating patch and the second radiating patch. The first radiating patch has a first extension part extending to an opposing side of the feeder.

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 dual-feed dual-band multiple-input and multiple-output (MIMO) antenna apparatus includes an antenna radiator, a first feed port, a second feed port, a first filter unit, and a second filter unit. The first feed port and the second feed port are spaced on the antenna radiator in a length direction of the antenna radiator. The first filter unit is disposed between the first feed port and the antenna radiator, and the second filter unit is disposed between the second feed port and the antenna radiator. The first filter unit is configured to pass a frequency component within a first preset frequency range, and filter out a frequency component outside the first preset frequency range; and the second filter unit is configured to filter out a frequency component within a second preset frequency range, and pass a frequency component outside the second preset frequency range.
