Abstract

The invention provides an antenna structure, which comprises a double-arm antenna and a main board, wherein the main board is connected with the double-arm antenna and is used for feeding electricity to the double-arm antenna; the double-arm antenna comprises a first arm, a second arm and a coupling branch; the first arm is used for achieving low-frequency resonance; the second arm is used for achieving high-frequency resonance; the first end of the first arm and the first end of the second arm are connected to the main board respectively; the coupling branch is parallel to the second arm and comprises a first branch part and a second branch part; the first branch part and a first part of the second arm are arranged side by side; the first part of the second arm forms one part, extending towards the first end, of the second end of the second arm; and the second branch part extends towards the direction far away from the first end of the second arm relative to the first branch part; and the second branch part is connected with the first arm. According to the antenna structure provided by the embodiment of the invention, the specific absorption rate SAR of the antenna is reduced; and the radiation injury to a human body is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to an antenna structure. Background technique [0002] SAR is specific absorption rate. Under the action of an external electromagnetic field, an induced electromagnetic field will be generated in the human body. Since various organs of the human body are lossy media, the electromagnetic field in the body will generate currents, resulting in the absorption and dissipation of electromagnetic energy. SAR is commonly used in biological dosimetry to characterize this physical process. SAR is defined as the electromagnetic power absorbed or consumed by a unit mass of human tissue, in W / kg. [0003] With the rapid development of wireless communication technology, wireless terminal (mobile phone, data card, MiFi / Hotspot) products have been widely used in daily life. At the same time, the public is increasingly concerned about the impact of electromagnetic radiation from wireless termi...
