## 3 Results  
In this paragraph, we describe the results obtained for the five different configurations evaluated in the frontal and orthogonal orientation of the phantom, in terms of SAR\({}_{\text{wb}}\) and SAR\({}_{\text{10g}}\). Furthermore, we remind readers that all the data and values reported in the present study are obtained by considering an input power of 30 dBm (1 W) for each of the two 5G-V2X antennas, as described in the Materials and Methods section. Figure 3 shows the distribution of SAR\({}_{\text{10g}}\) on the skin. For the sake of clarity, we displayed only the three cases where pSAR\({}_{\text{10g}}\) was higher than 1 mW/kg, namely, CONF 1 in the frontal and orthogonal orientations and CONF2 in the frontal orientation. These three cases correspond to Ella standing closer to the frontal antenna. The high exposure levels found in these three cases are mostly due to the field generated by the front 5G-V2X  
antenna (mounted on the car windscreen with a tilt angle of 37\({}^{\circ}\)), causing the main beam of the 5G-V2X antenna to be somewhat more directed to the phantom. As seen in Figure 3, in CONF 1, the highest SAR\({}_{\rm 10g}\) values are localized at the head, namely, at the nose and eyes in the frontal orientation and at the ear region in the orthogonal one, whereas the torso and the arms showed lower SAR\({}_{\rm 10g}\) values with respect to the head. In CONF2, in the frontal orientation, the highest exposure levels are localized in the right arm, that is, the body part that is closer to the frontal 5G-V2X antenna. As a general remark, we further noticed that, in all configurations (included those not shown in Figure 3), the highest SAR\({}_{\rm 10g}\) values were observed in the torso, arms and head area, whereas the legs showed almost negligible values. As for the exposure at the whole-body, the SAR\({}_{\rm wb}\) was well below the basic restriction limit of 0.08 W/kg and ranged from 0.001 mW/kg in CONF5 in the frontal orientation to 0.074 mW/kg in CONF1 in the frontal orientation. Figures 4-7 show the peak value and boxplot of the SAR\({}_{\rm 10g}\) distribution in the skin tissue, head skin tissue, whole brain and eyes, respectively. As a general comment, we notice that the highest pSAR\({}_{\rm 10g}\) values are always obtained in CONF 1 (that is, when Ella is in front of the car hood) for both orientations and all tissues. Moreover, as seen from the boxplot in Figures 4-7, for all tissues, configurations and orientations, the distribution of SAR\({}_{\rm 10g}\) exhibits a substantial positive skewness, meaning that SAR\({}_{\rm 10g}\) was mostly distributed towards low exposure levels. Figure 3: Distributions of SAR\({}_{\rm 10g}\) on the skin tissue for the three cases where pSAR\({}_{\rm 10g}\) was higher than 1 mW/kg. Note that the distributions in the three cases are normalized with respect to their pSAR\({}_{\rm 10g}\). Figure 4: SAR\({}_{10\text{g}}\) (left \(y\)-axis, box plot) and PSAR\({}_{10\text{g}}\) (right \(y\)-axis, square symbols) in the skin tissue over the whole body for the five different examined configurations, considering the frontal and orthogonal orientations of the Ella model. The center line in the boxes is the median; the bottom and top edges are the 25 th and 75 th percentiles. The lower whisker extends to the minimum value, while the upper whisker extends to 1.5 times the height of the box.
