In this paper a compact planar UWB antenna has been presented and characterised in frequency and time domain with respect to human body presence for applications in wireless body area networks (WBAN). The CPW-fed antenna performance agrees well with UWB requirements. The CPW-fed antenna demonstrated excellent characteristics, specifically for on-body propagation channels, considering the minimal change in path loss models slope values when body posture changes. A multi-slope linear power fit was proved to be most suitable for path loss modelling of the on-body channel due to changes in wave characteristics with distance from transmitter and also due to human body shadowing effect
