Abstract

In this work, a flexible radar absorber structure is presented which offers high absorbance within X band. The proposed structure is designed by integrating two different resonators which provides high angular-stability properties. The theoretical and experimental results indicate that the proposed absorber is polarization insensitive and angular stable up to 600 in both the TE and TM polarization cases. Apart from conventional absorptivity analysis, the cross-polarization reflection of the proposed absorber is also calculated. The simulated results indicate that the proposed FSS configuration behaves as proper absorber and not a polarization convertor. The Radar Cross Section (RCS) of the proposed absorber is also calculated and compared with the RCS of a reflective sheet to analyze its suitability for practical applications at 10.95 GHz frequency in X band. The fabricated absorber is also tested for different angle of bend to test the effects of its flexibility on absorption. The simulation and measurement results indicate that the proposed absorber is highly suitable for absorption application within X-band.
