Estimation of theLocation of metalical objects in mobile phoneESTIMATION OF THE OPTIMAL LOCATION OF METALLIC OBJECTS INSIDE A MOBILE PHONE
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
