Problems solved by technology

[0018] The above solutions to SAR are all obtained by changing the main antenna itself to obtain a low SAR result, but the specific implementation is very difficult for antenna designers

Embodiment Construction

[0031] Such as figure 1 As shown, the antenna provided by the embodiment of the present invention includes a main antenna (1), the main antenna (1) is installed on one side of a PCB (2), and an auxiliary antenna (3) is provided on the other side of the PCB (2), and The radiation directions of the main antenna (1) and the auxiliary antenna (3) are opposite, and the resonant frequency range of the auxiliary antenna (3) includes at least the resonant frequency range when the main antenna (1) has a high specific absorption rate.

[0032] The form of the auxiliary antenna (3) can be various, and it does not have to be the same as the main antenna (1). The auxiliary antenna (3) can have a separate matching circuit, can also share a matching circuit with the main antenna (1), or there is no matching circuit, and can also be directly printed on the PCB (2).

[0033] When people use hand-held communication devices to approach the brain, the antenna radiates energy to the brain, which is ha...

Abstract

The invention provides an antenna which comprises a main antenna that is installed at one side of a PCB; the antenna is characterized in that the other side of the PCB is provided with an auxiliary antenna. The antenna can realize that when the antenna engineer debugs out the best TRP without the consideration about antenna types, the auxiliary antenna is added to reduce specific absorption rate, thus reducing the difficulty in the design of the antenna and the specific absorption rate of the antenna as well as being simpler and more convenient.

Description

Technical field [0001] The present invention relates to an antenna, in particular to a technology for reducing the specific absorption rate of the antenna. Background technique [0002] In the past 50 years, scientists around the world have conducted in-depth studies on the health effects of radio wave radiation. The result is the establishment of safety standards and norms based on scientific data that are recognized as public health protection by countries around the world. These standards and norms are based on a comprehensive professional assessment of feasible scientific research, and their prescribed reflection limits take many safety into consideration. Factor, and is far below any reflection level that can affect health. Therefore, these standards can provide adequate security protection for users and the public. my country is the world's largest mobile phone country with nearly 400 million mobile phones. When using a mobile phone, it is very close to the human brain and ...
