**4.2 Analysis of near-field coupling from antenna to embedded devices**

Since the antenna is usually implemenred in the proximity of TP and camera, the near-field coupling to the nearby TP and camera would sometimes result in malfuction due to the transmitted power (Figure 21). The electromagnetic field distribution on TP due to antennaradiation is shown in Figure 22 below.
