Abstract: An antenna, an antenna control method, and a terminal, where the antenna includes an antenna body and an antenna branch, where one end of the antenna branch is coupled to the antenna body, the other end is coupled to a feedpoint of a primary radio frequency channel, and the end of the antenna branch that is coupled to the feedpoint of the primary radio frequency channel is further coupled to the antenna body through a first adjustable device, where the first adjustable device is in an on state or an off state. An antenna branch is coupled between the feedpoint of the primary radio frequency channel and the antenna body, and the antenna branch is capable of coupling or decoupling by switching on or off the first adjustable device.

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.
