In addition, a UWB antenna is preferentially non-
dispersive, having a fixed phase center. If waveform
dispersion occurs in a predictable fashion it may be
possible to compensate for it, but in general it is desirable
to radiate similar waveforms in all directions. A log-
periodic antenna is an example of a dispersive antenna.
Larger scale components radiate low frequency
components while smaller scale components radiate high
frequency components. The result is a chirp-like,
dispersive waveform. Worse, the waveform will vary at
different azimuthal angles around the antenna. Again, a
multi-band or OFDM approach may be more tolerant of
dispersive antennas.
