9 gru 2020 · The performance of printed wideband antennas has to be optimized both in frequency and time domains, to qualify for UWB applications. This is especially true in multi-resonant antenna topologies where the excitation of different modes can change phase centers and radiation patterns with frequency.

The use of very short RF pulses. Since short pulses have very wide frequency bandwidth, it is termed “Ultra WideBand” or “UWB”. FCC defines UWB as a 10 dB bandwidth > 500 MHz or > 20%. TDC’s systems are typically > 2 GHz and > 60%. Actual UWB Pulse and Its Spectrum.
