Design of UWB antipodal Vivaldi antenna with rectangular corrugated edges for through wall imaging (TWI) applications

An Ultra-wideband (UWB) rectangular corrugated edges antipodal Vivaldi antenna (RCE-AVA) designed for through wall imaging applications is demonstrated. In this study, two distinct designs for antipodal Vivaldi antennas are reported: a conventional AVA and a rectangular corrugated edges AVA. In th...
