Abstract: A terminal antenna includes a first radiator. The first radiator includes N radiating elements connected end to end, where N is an integer greater than or equal to 2. One end of any one of the radiating elements is grounded through a reactance element. The N radiating elements include a first radiating element, and a feed is arranged at one end of the first radiating element away from the reactance element.

Abstract: Embodiments of this application provide a low-SAR antenna and an electronic device, which relates to the field of electronic devices and can provide good radiation performance at middle/high frequencies and have a low SAR value. The specific solution is as follows. A first radiation structure includes a first radiator, and a second radiation structure includes a second radiator. A first end of the first radiator and a first end of the second radiator form a first gap. A second end of the first radiator is free, and a second end of the second radiator is grounded. A feed point of the antenna is coupled to the first radiator, and the first radiator is divided into a first portion and a second portion that are delimited by the feed point. In a case that the antenna is in operation, the first portion of the first radiator and the second radiator work together in a first frequency band and a second frequency band, and a frequency of the first frequency band is less than a frequency of the second frequency band.

Abstract: Embodiments of this application relate to the field of antennas, and provide a terminal antenna. The terminal antenna includes n radiators. The n radiators include a first radiator, a second radiator, and a third radiator. Lengths of the first radiator, the second radiator, and the third radiator form a descending arithmetic progression. The first radiator, the second radiator, and the third radiator are arranged in sequence to form two gaps. A coupling capacitance formed by the first radiator and the second radiator through the corresponding gap is greater than a coupling capacitance formed by the second radiator and the third radiator through the corresponding gap. The first radiator, the second radiator, and the third radiator are any three of the n radiators distributed in sequence.

Abstract: This application provides an antenna decoupling structure, a MIMO antenna, and a terminal. The antenna decoupling structure includes a grounding stub and a capacitor structure, where a first end of the grounding stub is connected to an antenna floor, to form an equivalent inductor; and a first end of the capacitor structure is connected to the antenna floor, and a second end of the capacitor structure is connected to a second end of the grounding stub, so that the equivalent inductor and the capacitor structure form an LC resonant structure, where a parameter corresponding to the LC resonant structure meets a decoupling requirement for at least one target decoupling frequency band. Because the resonant frequency depends on the inductance and the capacitance that correspond to the LC resonant structure, antenna miniaturization can be realized by reducing a size of each portion of the decoupling structure.

Abstract: This application discloses a multi-antenna system and a wireless communication device. The multi-antenna system includes a first antenna, a second antenna. A first extension branch is close to the second antenna, and a second extension branch is close to the first antenna. A feed of the first antenna is disposed on the first radiator, and a feed of the second antenna is disposed on a second radiator. A feed of the third antenna is disposed at the first extension branch. There is a spacing between the first extension branch and the second extension branch. An equivalent circuit of the spacing includes a distributed capacitor. The distributed capacitor is configured to isolate signal coupling between the first antenna and the second antenna when a first resonant frequency of the first antenna and a second resonant frequency of the second antenna are within a preset frequency range.
