Abstract
In this paper, we present the design of an ultra-wideband Vivaldi array for a reconfigurable STW application utilizing an imaging radar system to view images through walls comprised of various types of materials. The proposed Vivaldi array, fed by four-section Wilkinson power dividers, demonstrates a frequency band of 1-10 GHz and acceptable radiation patterns over the entire operation band.
