Abstract

The free space transmission estimation of ultra wideband impulse radio (UWB-IR) was developed by using the extension of Friis´ transmission formula [1]. It considered the transmitted waveform and its distortion due to the channel and the transmitter (Tx) and receiver (Rx) antennas for the free space link budget evaluation of UWB-IR. This paper presents the two path evaluation formula of the ground reflection path loss for UWB-IR systems that based on the extension of Friss´ transmission formula. Since the antennas are the pulse-shaping filters in UWB-IR systems, the biconical antennas are experimentally examined, especially focusing the effect of template waveforms.
