An improved Adaptive Frequency Sweeping Method for Wide-band Antenna Array Simulation

In this paper, an improved adaptive frequency sweeping method for wide-band antenna array simulation is proposed. This method combines rational vector-fitting with matrix interpolation method. For wide band simulation, the combination frequency sweeping method has high efficiency, only a few frequency points are required even for a wide band simulation. To validate this method, an example of antenna array for 5G application is given to demonstrate the efficiency of the proposed method.
