Paper Abstract

A systematic theory for estimating ultra-wideband antenna parameters and performance is not yet published. Because the radiation of short duration signals is significantly different from the long duration narrowband signals, we analyzed the processes in linear antennas and give a physical interpretation. We considered a series excited antenna modeled as one branch of a symmetrical radiator of length L, and having a large number of elementary radiators of size (Delta) L. By examining the radiation from each element (Delta) L, we can sum the results and provide a far field estimate at different angles from the antenna axis. The result shows the field is a function of time and angular position from the antenna, instead of position, as in the narrowband case. For a given radiator size L, the radiation because axial for small values of c(tau) . As (tau) increases for a constant length, the pattern becomes normal to the antenna axis.
