Abstract

The invention discloses an SAR reducing antenna comprising an antenna part, a feeding point and a grounding point. The antenna part comprises a feeding part connected with the feeding point, a grounding part connected with the grounding point, an antenna radiation part and a regulating radiation part. The antenna radiation part comprises an equipment metal frame. The feeding part is connected withthe metal frame through a metal line so as to parasitize a resonance signal. The regulating radiation part is connected with the metal frame and used for receiving the radiation energy of the metal frame.

Description

technical field [0001] The invention relates to the communication field, in particular to a SAR-reducing antenna and a communication device with the SAR-reducing antenna. Background technique [0002] Miniaturized multi-band built-in antennas have always been the development direction of handheld communication terminal antennas. The existing antenna forms include multi-frequency monopole antenna (monopole antenna), single loop or dual loop antenna (single loop and dual loop antenna), inverted folded antenna (IFA), planar inverted folded antenna (PIFA). These antenna types are different Each handheld communication terminal environment has its own conditions and performance. Different antenna forms can be selected according to different requirements. [0003] Usually mobile terminal equipment includes GSM850 / 900, DCS, PCS, UMTS, and its frequency range is 0.824GHz-0.96GHz, 1.71GHz-2.17GHz. With the continuous development of LTE technology, 3.5GHz and 4GHz have attracted muc...
