This paper presents an EMC modelling approach for the latest dual die CPU with a heatsink from an antenna point of view. The model acts as a very efficient antenna while its structure is constructed almost according to a real dual die CPU structure. Different sizes of heatsink cooperate in the investigation of electromagnetic characterization. Simulation and measurement are accomplished in far-filed range. The results show that the dual die model without heatsink is resonating at two frequencies which are 2.04GHz and 4.9GHz. When a heatsink is mounted however the resonant frequencies are changed to 1.80GHz and ...
