Radiating dipole antenna with tapered impedance loading

The far-field radiated waveform and field pattern from a thin dipole antenna in the transmission line approximation are considered when the antenna is driven by a voltage generator of waveform
V_{0}u(t)
, where
u(t)
is the unit step function. The antenna is loaded with a tapered form of loading and is permitted to include reactance as well as resistance. Analytical and numerical solutions for the far-field pattern and waveform are discussed. In particular, the effects of parallel resistive and inductive loading are presented.
