A full-wave model based on the electric dyadic Green's function has been used to analyze the response of a microstrip line excited in the near field of an electrically short dipolar source. Using the moment method, the surface current excited on the strip has been computed. It has been found that considerable effects are produced by the interaction of the microstrip line with the near-field source's components. The current induced along a microstrip line as well as at its loads has been evaluated for different positions and polarizations of the dipolar source. The numerical results indicate that only a full-wave model which takes into account both the surface and volume waves excited in the structure can be used to evaluate the influence of the electric and geometric parameters, and/or to determine the position of other passive and/or active components that reduces the induced disturbances.
