Early-time response of the spherical antenna

The early-time response of the spherical antenna is determined by a two-step process. First, the high-frequency representation is derived by the technique known as the Watson transformation. The high-frequency results are then Fourier transformed to obtain the time response. The time region where these results are valid is given and comparisons to previous analyses are made. Conclusions regarding the utility of this method to other antenna shapes and different time regions are discussed.
