(A) low RCS vivaldi antenna array of honeycomb sandwich type

Abstract

The ability to stealthily penetrate enemy lines is critical to gaining the upper hand in warfare, especially the ability to evade enemy radar surveillance networks. Antennas are the typical part that degrades electromagnetic stealth performance, and new forms of antennas are needed to maintain antenna performance while having low RCS. In this study, a sandwich type low RCS honeycomb Vivaldi antenna array was proposed. When designing a low RCS honeycomb Vivaldi antenna array using a honeycomb Vivaldi antenna array and nickel-coated glass fiber as a sandwich type, the antenna gain and RCS were confirmed through simulation and measurement, and the possibility was examined.
