Antipodal Vivaldi antenna array with reduced mutual coupling for UWB radar applications

In this paper an array based on an Antipodal Vivaldi Antenna (AVA) is presented. Two different types of arrays have been studied in order to obtain a small configuration with reduced mutual coupling. The first is 1×8 elements in the H-plane and the second is 8×1 elements with planar configuration. The antenna arrays are optimized to have a compact and small size, improved gain and reduced mutual coupling.
