Embodiment Construction

[0047] Generally speaking, multiple antennas may be provided in an electronic device for performing wireless communications in different frequency bands.

[0048] Exemplarily, among the multiple antennas of the electronic device, an antenna (for example, referred to as a main antenna) used for communication at a main frequency (covering a frequency of 700 MHz-3 GHz) may be included. Take the electronic device as a mobile phone as an example. When the main antenna is arranged at the lower part of the mobile phone, the antenna will be covered by the user's hand holding the mobile phone, which will lead to deterioration of the performance of the antenna.

[0049] In some designs, the main antenna can be arranged on the upper part of the electronic device, so as to avoid the influence on the radiation performance of the antenna when the user holds the electronic device.

[0050] Exemplary, combined with figure 1 , is a schematic diagram of an antenna setup for an electronic devi...

Abstract

The embodiment of the invention discloses a low-SAR antenna and electronic equipment, and relates to the field of electronic equipment. Better medium-high frequency radiation performance can be provided, and the SAR value is low. According to the specific scheme, a first radiation structure comprises a first radiator, and a second radiation structure comprises a second radiator. The first end of the first radiator and the first end of the second radiator form a first gap. The second end of the first radiator is suspended, and the second end of the second radiator is grounded. The feeding point of the antenna is coupled with the first radiator, and the first radiator is divided into a first part and a second part by taking the feeding point as a boundary. When the antenna works, the first part of the first radiator and the second radiator work in a first frequency band and a second frequency band together, and the frequency of the first frequency band is lower than that of the second frequency band.

Description

technical field [0001] The present application relates to the field of electronic equipment, in particular to a low SAR antenna and electronic equipment. Background technique [0002] The electronic device can transmit and receive wireless signals through the antenna provided therein. The radiation performance of the antenna is closely related to the environment of the antenna in the electronic equipment. For example, when the antenna is arranged at the lower part of the electronic device, the antenna will be covered by the electronic device held by the user, which will greatly affect the radiation performance of the antenna; thus affecting the communication experience when the user holds the electronic device. [0003] At present, the antenna can be arranged on the upper part of the electronic device, so as to avoid the influence on the radiation performance of the antenna by holding the electronic device. [0004] It is understandable that when an electronic device is wo...
