Radar Cross Section Reduction of Microstrip Antenna Using Dual-Band Metamaterial Absorber

摘要

This paper deals with the design and experimental verification of a dual-band metamaterial radar absorbing structure for the reduction of radar cross section (RCS) of a microstrip antenna. A Metamaterial Absorber (MMA) is designed to work in X-band with absorption rate near 100%. To demonstrate the effective performance of the proposed structure, its influence on RCS and performance of a microstrip antenna is investigated. According to the numerical and measurement results, one can find that the designed antenna shows dual-band RCS reduction within X-band for wide incident angles, while the radiation characteristics of the antenna are sustained without undesired changes.
