Abstract

The invention provides an antenna device and a communication device using the antenna device. The communication device comprises a circuit board, a first antenna and a metal sheet. The circuit board is provided with a first feed-in point connected with a high-frequency unit, the first antenna is provided with a first radiation portion coupled with the first feed-in point, the metal sheet is connected with the ground and arranged in a mode of corresponding to a projection shape of the first radiation portion, a gap is arranged between the metal sheet and the first radiation portion, and the metal sheet is larger than or equal to the projection of the first radiation portion in area. The structure is used for reducing SAR values.

Description

technical field [0001] The present invention relates to an antenna device and a communication device using the same, and in particular to an antenna device capable of reducing the Specific Absorption Rate (SAR) value of electromagnetic waves and a communication device using the same. Background technique [0002] Today's mobile communication devices are mostly designed in the direction of thinness, lightness and compactness. Some mobile communication devices are equipped with two antennas, which can send and receive signals at the same time to provide more diverse applications. The radiation of the antenna of the mobile communication device must pass the detection of the Specific Absorption Rate (SAR) to prevent the human body from absorbing too much electromagnetic radiation. [0003] There are currently three techniques for reducing the SAR value. The first method is to reduce the electromagnetic wave radiation and reduce the SAR value by reducing the conductive power of...
