On the radiated electromagnetic emission modelling of on-chip microwave components

A radiated emission model, scaled, optimized, and compatible to modelling “on-chip” microwave devices is presented in this paper. The model has been inspired from a previously existing model at IRSEEM, which predicts only the radiated magnetic field. The proposed model predicts the radiated electromagnetic (EM) emissions of components of very small form factor. An optimization procedure has been implemented in order to extract the model parameters, taking into account their physical sense. The model is applied to an “on-chip” microstrip patch antenna, designed and simulated in Ansoft HFSS. The antenna is built on a High Resistivity Silicon substrate and resonates at 20 GHz. Promising and encouraging results have been obtained for the modelled radiated EM fields. Our model is proven suitable to apply on System-in-package and System-on-Chip devices integrating wireless system within itself.
