Abstract :
In this work an analysis of a coaxial TEM horn with loaded dielectric coupling structure is proposed, which is excited by pulsed signal with short duration. Due to the circularly symmetry of this horn a bi-dimensional analysis with FDTD technique was possible, and the results for the radiation pattern are compared with measurements.
