Use of the Coupling Between Elements of the Vertical Antenna Array of LCRs to Gain Radiation Efficiency for UWB Pulses

The inductance of large current radiators (LCRs) can be reduced by stacking several of them as a vertical array. The reduced inductance permits a shorter rise time for the driving current. Both theory and experimental data show that the radiated field strengths are increased considerably for a fixed, small driving voltage.
