摘要：
A new method for the calculation of transient field radiated through aperture antennas is described. The Finite-Difference Time-Domain method is applied for the near field Prediction in the close surrounding of the antenna and a proper parametrization of the aperture field by space- and time-variant basis functions permits to obtain closed-form far field formulas which are separable with regard to space and time. The feasibility of the method is discussed by application to the time and frequency domain analysis of a broadband circular ridged horn antenna in both standalone and array configurations.
