Design of compact directive ultra wideband antipodal antenna

Abstract

Abstract In this paper, a novel design procedure for designing a compact UWB antipodal Vivaldi antenna is presented. The antenna operates over the UWB frequency band from 3.1 to more than 10.6 GHz. Its measured far‐field radiation is directive and its peak gain is 10.2 dBi in the specified band. The antenna pulse response shows negligible distortion, indicating that it can be useful in a precision ranging and imaging instrumentation. © 2006 Wiley Periodicals, Inc.
