*2.1.2 Signal dispertion ans distortion*

The signal passing through the UWB antennas is a very short pulse, the shorter the pulse is more likely the UWB antenna's response is going to be distorted and delayed due to the ripple after the pulse called the rippel effect [5].

The rippling effect is caused by the geometry of the antenna, and it causes frequency translation, dispersion or delay on the transition reducing the speed of data transmission [6].
