Popis: A new model for fixed ground-signal-ground (GSG) pad is presented in this paper. The circuit model of RL ladder and RL series is used to model the skin and proximity effect of the GSG pad. This lumped element circuit model does not only characterize the skin and proximity effect of the pad but also explicitly models the series impedance effect of the pad at millimeter-wave frequencies. The pad has been designed and fabricated based on 40 nm CMOS technology. The HFSS EM simulation result shows that the maximum radiation pattern of the pad at 50 GHz of phi 90° is at the right angles with the axis of the pad field. The model parameters are directly derived through processed parameter optimization algorithms. The performance of the proposed model illustrates excellent agreement with the measurement data up to 50 GHz. Hence the root-mean-square error of the model with measured data is 0.02356.
