Abstract

The invention relates to a communication device, comprising a first circuit board, a second circuit board and an antenna. The first circuit board is arranged on the second circuit board, and is electrically connected with the second circuit board by a connecting point. The first circuit board comprises a clear zone, a plurality of key pads and a plurality of inductors, wherein the key pads correspond to the clear zone, and the inductors are respectively connected between the key pads in series for regulating the inductance of the key pads. The antenna comprises a radiation metal sheet which corresponds to the clear zone and is positioned at one side of the second circuit board so as to receive and transmit wireless signals. By the communication device, SAR value can be effectively reduced,and the design elasticity of the antenna limited by the design of the dimension of the communication device is increased.

Description

Technical field [0001] The present invention relates to a communication device, in particular to a communication device that can reduce the Specific Absorption Rate (SAR). Background technique [0002] With the rapid development of wireless communication technology, various communication products, such as mobile phones, mobile Internet devices (MID), netbooks, and other electronic devices with integrated wireless communication functions, have become increasingly popular. Antennas are the most important element in communication devices. They are classified according to whether they are exposed outside the case. They can be divided into hidden antennas and exposed antennas. The use of hidden antennas can make the antennas less susceptible to damage due to external forces, and the product appearance More beautiful. [0003] However, the size of current communication devices is designed to be light, thin and short. When designing built-in antennas in a limited space, the placement pos...
