Efficient and practical pulses for dipole antenna UWB link

A full-wave UWB link simulator with accompanying post-processing tools has been developed to study the effects of signal waveform and antenna geometry. In this paper, we focus on analysis/synthesis of suitable UWB signaling schemes to be implemented in a low-complexity antenna/circuitry co-design. When the antenna characteristics are known, it is possible to design waveforms that optimize some aspect of a UWB link. However, the optimized waveform often is complicated and difficult to implement with simple circuitry. We show below that simple windows applied to the time waveforms and frequency spectrum can produce UWB pulses that: (1) control the spectral power density of radiated fields and received voltage; (2) create large peak received voltage; and (3) confine received energy to a narrow time interval.
