Pulse-receiving characteristics of resistively loaded dipole antennas

The pulse-receiving characteristics of resistively loaded dipoles are analyzed using a time-domain numerical technique. The Wu-King nonreflecting dipole and several other dipoles with higher and lower distributed resistances are considered. The time-domain responses of these dipoles to Gaussian electromagnetic pulses (incident in boresite direction) are calculated. Frequency-domain receiving transfer functions are obtained using the fast Fourier transform (FFT) technique. Dipoles terminated with high resistance loads are also considered. The effect of the distributed resistance and terminal resistance on the pulse response and bandwidth is discussed.<
