Extension of the analytical modelling of resistive loaded thin-wire antennas to Gaussian derivatives excitations

The transient electric field radiated from a thin-wire dipole antenna resistively loaded and excited by a voltage signal in the shape of the Gaussian derivatives is analyzed. The modelling presented in this paper is formulated in the time domain using all inverse Fourier transform of the analytical expressions obtained by Wu and King in the frequency domain. Such a modelling appears as all extension of previous developments, as it allows its to consider any Gaussian derivatives as excitation signals as well as the presence of a nonnegligible impedance in the feeding circuit. parameter studies are presented to analyze the waveforms and the energy radiated in the far-field zone.
