In order to improve the stealth performance of antenna, a metamaterial absorber with high absorption, polarization-insensitive and wide angle based on the electromagnetic resonance is designed. Using of ultra-thin characteristic of absorber, they are attached to the microstrip antenna to reduce its radar cross section. The simulation results show that the new microstrip antenna’s radiation performance remains unchanged compared with conventional microstrip antenna and it has obvious RCS reduction in its working band. While the maximum reduction can reach 28dB at working frequency, and the in-band reduction of antenna is above 3dB. This indicates that the absorber can be used for antennas’ in-band stealth.

High Absorption

A new development of metamaterial applications in radar absorbers for X band is introduced. Two modifications were suggested based on two different approaches which are a new called fan shaped resonator absorber and a modified high impedance metamaterial absorber. Both approaches introduce thin radar absorber (5.3% at centre frequency) with wide bandwidth and high absorption level. The theoretical concepts of each design are explained and validated using full wave simulation. Results illustrate that the new development can achieve wider bandwidth, multiple operating bands; the increase in bandwidth is up to 8 times the conventional one. Moreover, the reported absorbers have capability to operate with different polarizations.

High Absorption

We demonstrate a dual-band, polarization-insensitive, ultrathin and flexible metamaterial absorber (MA), based on high-order magnetic resonance. By exploiting a flexible polyimide substrate, the thickness of MA came to be 1/148 of the working wavelength. The absorption performance of the proposed structure was investigated for both planar and bending models. In the case of the planar model, a single peak was achieved at a frequency of 4.3 GHz, with an absorption of 98%. Furthermore, additional high-order absorption peaks were obtained by the bending structure on a cylindrical surface, while the fundamental peak with a high absorption was maintained well. Our work might be useful for the realization and the development of future devices, such as emitters, detectors, sensors, and energy converters.
