Using partial image expansion allows to include the substrate directly in the equivalent model, that is composed of PEC plane, substrate and dipole sources. The addition of the dielectric increases the model versatility allowing for a wider range of simulations to be run (e.g. closed environments, multiple boards, etc.). In this paper, the radiation model of the physical device is obtained and imported in a commercial full-wave solver (HFSS). The simulation results are finally compared with the original measurements, experimentally validating the accuracy of an IDM built using partial image expansion.enInfinitesimal dipole modelMethod of ImagesNear-field scanningPrinted circuit boards (PCB)Radiated fieldsTechnology::621: Applied Physics::621.3: Electrical Engineering, Electronic EngineeringConference Paper10.23919/EMCJapan/APEMCOkinaw58965.2024.10585137https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10585137Conference Paper
