Abstract :
In this presentation, we introduce a new approach to beam-steering of short, ultrawideband (UWB) pulses using a single-feed radiating structure. With a radiator consisting of small apertures backed by a reverberating cavity (Fig.1), a time-reversal (TR) technique is applied to generate a short pulse at each aperture with the corresponding time-delay for beamforming at a desired steering angle.
