Summary:
This paper is studying the phase distortion due to antenna on free space transmission in UWBIR system. We develop the free space link budget evaluation scheme in the term of frequency transfer function for UWB-IR system that takes into account the transmitted waveform, its distortion due to the antennas, the channel and the correlation receiver. Root raised cosine passband waveform is used as the UWB-IR transmitted waveform. Experimental investigations are done for different types of the antennas. The distortion quantities in the terms of phase are defined and shown. This scheme provides some useful physical insights and optimized design procedure with clear and accessible description of the UWB-IR link budget comprised of practical antennas.
