Radio Frequency Interference Estimation using Transfer Function Based Dipole Moment Model

Abstract

Dipole moment model is widely used to represent real noise source to estimate near field coupling between noise source and the victim antenna. However, direct full wave simulation of large number of dipole moment is often very time-consuming. Also, another set of full wave simulation is needed if parameters change. A more scalable approach is needed. In this paper, a transfer function based dipole moment model is proposed to solve this issue. The proposed method only needs one-time full wave simulation. The results obtained from this one-time simulation can be reused for other cases if the same antenna structure is used. The proposed method will use the simulation results to construct transfer functions. The method is implemented in CST where several high performance computing methods are available. The validation of a test board with both simulation and measurement data is also provided.
