    Impulse radio (IR) transmission is consider used in wireless personal area network (WPAN) for high speed and low power transmission and new innovation wireless technology. This paper propose a novel analysis of impulse radio transmission in WPAN for ultra wireless communications. The waveform distortion due to the antennas should be considered. The optimum and isotropic template receivers are considered based on Friis transmission formula. In this experimental study, the biconical antennas are uesd as the transmitter (Tx) and the receiver (Rx) antennas. The rectangular passband, which is satisfied the full band of UWB-IR definition and Federal Communications Commission (FCC) indoor limit spectral masks, is used as the transmitted waveform of UWB system. The channels are measured in an anechoic chamber by using a vector network analyzer (VNA). The measured data are evaluated in path loss of optimal and isotropic template receivers, the IR transmission gains and BER are shown and compared in results.
