Ultrawide-band (UWB) is a new technology that transmits very low energy levels broadband pulses allowing for short-range high-bandwidth communications. In the United States, the Federal Communications Commission FCC [1] authorized the unlicensed use of the 3.1–10.6 GHz spectrum for UWB applications with limited power spectral density emission to enable spectrum sharing with other established narrowband applications without mutual interference. However, in some environments, UWB systems require the inclusion of band-rejection filters to avoid the possible interference from preestablished wireless local area networks (WLAN), allocated from 5.15 GHz to 5.825 GHz.
