Nemec ABSTRACT The propagations of electromagnetic waves through obstacles are analyzed. Narrow band and ultra wide band (UWB) propagations are compared. It is shown that for propagation studies it is necessary to consider not only propagation for a single frequency (narrow band propagation) but UWB signals and effect of antenna receiving and transmitting responses for various antenna types (such as small and aperture antennas) have to be considered.
