In this work, a quantitative analysis of the electromagnetic fields in the vicinity of a patch and slot antenna, excited at 24 GHz, is conducted. The spatial decay of the electric and magnetic fields as well as the power density is evaluated on top of the substrate where other package/board components can be integrated. The results reveal that the spatial decay of the fields is qualitatively similar for both antenna types. Based on this analysis, favourable component positions in the vicinity of the antennas can be deduced with the aim of ensuring electromagnetic reliability (EMR).
