Abstract :
A short transverse electromagnetic (TEM) horn with continuously tapered resistive loading was developed for directional reception or transmission of picosecond pulses with minimal distortion. It was found to be broadband and nondispersive with a low VSWR. The receiving transient response of the resistively loaded "TEM" horn indicates that the waveform of a 70-ps impluse is well preserved. The theoretical analyses using the method of moments and the fast Fourier transform (FFT) technique were performed and agreed well with time-domain measurements.
