Mobile terminal and antenna component based on mobile terminal

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...

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 test distance should be 0mm (direct contact model), and the SAR value can be reduced by reducing the conduction power of the terminal through the control of the processor. This solution can improve the SAR value to a certain extent, but at the expense of At the expense of antenna performance and at the same time need to increase the cost; for CE certification, the test distance should be 5mm (direct contact model) test, also exists in the same problem as FCC certification, so there is no suitable way to solve it this problem
