Meaning
Grid positions of maximum electromagnetic absorption within simulated tissue are identified during safety evaluations. The spatial peak coordinates mark the location where the highest SAR value is recorded by the test system.
Localized Hotspots
Pinpointing the area of maximum energy absorption is essential for analyzing the antenna performance. Identifying the spatial peak coordinates allows test engineers to focus subsequent high-resolution measurements on the most critical area. This targeted scan is known as the zoom scan.
Robot Alignment
Positioning systems use the discovered peak location to align the measurement probe for detailed scans. The measurement software uses the spatial peak coordinates to center the 3D grid scan. This centering ensures the robotic arm sweeps the highest exposure region accurately, preventing underestimation of the peak SAR.
Design Optimization
Hardware designers use localized absorption data to modify the internal layout of radiating elements. Knowing the spatial peak coordinates helps engineers reposition the antenna or add shielding to disperse the electromagnetic energy. This dispersion lowers the maximum concentrated absorption without requiring a reduction in the total radiated power.
Consequently, tracking these coordinates through different board iterations allows the design team to achieve both high wireless performance and full regulatory compliance before the product undergoes formal certification.
