Problems solved by technology

The problem brought by the existing technology is that there is always a contradiction between OTA and SAR values, and too high OTA often leads to high SAR values
At present, a commonly used method is to add a distance sensor as a switch to sense the approach of the human body, so as to reduce the conduction power of the processor to reduce the SAR value. In the FCC certification of the terminal for the Federal Communications Commission (Federal Communications Commission) for the body type For equipment SAR evaluation, the t

Example Embodiment

[0022] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0023] Such as figure 1 with figure 2 As shown, in order to facilitate understanding, first define each view, where figure 1 The mark B in the middle is the front, figure 2 The mark A is the back side, the mark C is the right side, the mark D is the lower side, the mark E is the left side, and the mark F is the upper side. When the mobile terminal has an antenna, both FCC and CE certifications have radiation to the human body. The index SAR value has made mandatory requirements. The certification specification requires testing to include the SAR values ​​on the left, right, top, bottom and back sides, and the front side is not tested by default (the front side of a tablet larger than 7 inches or containing 7 inches or more is not tested by default). For the left, right, upper and lower sides and the back side, depending on the position of the antenna, which s...

Abstract

The invention provides an antenna component based on a mobile terminal. The antenna component comprises an antenna arranged in the mobile terminal. The antenna comprises two groups of antenna branches. At least one group of antenna branch is arranged at the lower side of the back surface of the front shell of the mobile terminal. The invention also provides the mobile terminal which is equipped with the antenna component. Compared with the antenna components in the prior art, at least one group of antenna branch is arranged at the lower side of the back surface of the front shell so that the person is enabled to have a certain spatial distance from the antenna when the person is close to the terminal, the radiation of the antenna to the human body can be reduced, the OTA requirements of the antenna can be met and the requirement of reducing the SAR value can be met, the process of using a distance sensor to act as a switch control processor to reduce power can also be eliminated and thus the cost can be reduced.

Description

technical field [0001] The invention relates to an antenna technology, in particular to a mobile terminal and an antenna assembly based on the mobile terminal. Background technique [0002] In the prior art, the antennas of most communication tablet devices need to meet the requirements of radio frequency performance (OTA) and radiation index (SAR value), especially for some foreign operators, the requirements for OTA and SAR value are very high , are equally important. The problem brought by the existing technology is that there is always a contradiction between the OTA and the SAR value, and an excessively high OTA often leads to a high SAR value. At present, a commonly used method is to add a distance sensor as a switch to sense the approach of the human body, so as to reduce the conduction power of the processor to reduce the SAR value. In the FCC certification of the terminal for the Federal Communications Commission (Federal Communications Commission) for the body typ...
