Abstract :
Large area radiators such as the duoconical monopole are less frequency sensitive than thin antennas. The dispersive nature of antennas is important especially when they are used to transmit video pulses. This paper presents the numerical results obtained for the duoconical monopole under pulsed excitation. Results include the current distribution on the monopole at different instants of time, the radiated waveforms in different directions, and the waveforms of transmitted and reflected signals on the feeding coaxial line. Numerical results were obtained by applying the inverse Fourier transform to the steady-state time harmonic current distributions and radiation patterns. The above results are then used to find a simple incident voltage waveform that will radiate a "pulse" of "good" shape. The radiated field in different directions are then presented for different parameters of the incident double exponential voltage waveform.
