【简　介】:手机中金属器件的放置位置对天线的影响，具有一定的指导意义。
【目　录】:Planar near-field measurements of the electric field components are used to determine where to place external components, such as a loudspeaker or camera, without significantly affecting the radiated
field. The location of the peak value of the electric field is discussed. The three principal electric field components are simulated in order to illustrate which of the individual components contributes the most to the total field. The measured and simulated results are compared and discussed in terms of the
radiation from the planar inverted-F antenna (PIFA) element itself and from the ground plane of the antenna. The study shows that the optimal location of a camera or a loudspeaker can be determined directly from the raw, unprocessed, electric near-field distribution. The result is that metallic objects
should be located in areas below local minima in the electric field amplitude of the total field.

有没有专家讲解一下：电池、连接器、屏蔽罩等距离天线的距离数值对天线性能的影响？
