Stochastic differential equations (SDEs) are used to model ultrawideband (UWB) indoor wireless channels. We show that the impulse responses for time-varying indoor wireless channels can be approximated in a mean-square sense as close as desired by im

Introduction Interest in ultra-wideband (UWB) technology has increased significantly since the Federal Communications Commission's (FCC's) inquiry in 1998 and approval of its use in 2002. The FCC opened up two bands, the 3.1- to 10.6- and 22- to 29-G

Ultra wideband components have been developed using SIW technology. The various newly developed components include a GCPW transition, Y and T-junctions. The GCPW transition covers over 10GHz bandwidth with less than 0.4dB insertion loss. The optimize

Two different types of Vivaldi antenna arrays have been designed for UWB see through wall applications. The first is a 16 × 1 antipodal Vivaldi antenna covering 8-12 GHz, and the second is an 8×1 tapered slot antenna for 2-4 GHz frequency range. Th
