UWB derives its name from its wide bandwidth, 500 MHz or wider. This ultra-wide bandwidth in the frequency domain, translates into extremely short, nano-second pulses in the time domain, giving UWB its unique capability to measure distances with an accuracy of tens of centimeters.

22 mar 2021 · How UWB Works: Once two devices having UWB enabled placed near each other and start ranging. Ranging can be also be considered as calculating the time of flight between the two devices. UWB was also known as pulse radio in early times.
UWB is an IEEE 802.15.4a/z standard technology optimized for secure micro-location-based applications. It enables distance and location to be calculated indoors or outdoors with unprecedented accuracy – within a few centimeters – by measuring the time it takes radio signals to travel between devices. Along with centimeter-level
This book presents the theory, analysis, and design of ultra-wideband (UWB) radar and sensor systems (in short, UWB systems) and their components. UWB systems find numerous applications in the military, security, civilian, commercial and medicine fields.
One approach involves the measurement of a UWB signal’s temporal (time domain) characteristics. Digital signal processing (e.g. Fast Fourier Transform (FFT)) is then applied to transform the measured temporal parameters to their frequency domain representation. Once the UWB signal has
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.
