Study on pulsed radiating characteristics of doublet antenna loaded by lumped resistors with FDTD method

The pulsed radiating characteristics of a doublet antenna loaded by Wu-King lumped resistors are studied by the 3D FDTD method. The electric current waveforms on the antenna and the far field radiation patterns are all given. The results illustrate that this loaded form can certainly improve the pulsed radiating waveform in space.
