Abstract:

This paper presents a left-handed metamaterials (LHM) applied to reduce the RCS of the antenna. The LHM structure is utilized to the antenna by null-refraction assembly, and two simulated examples are provided. Simulated results show that at the working frequency the RCS of the array antenna with RAM can be reduced more than 20dB by this method. And the control of the RCS of the antenna can be obtained by adjusting the size of the LHM structure.

Key words: left-handed metamaterials, RCS reduction, refraction assembly
