Abstract
This work presents dual band, polarization insensitive and angular stable radar absorber structure. Here, proposed absorber unit cell has two resonator structures M and N. Each resonator provides absorption at distinct frequencies in X and Ku band. Simulation results in different cases show that the structure is polarization insensitive and angular stable up to 60 0 . Calculated effective impedance plot and surface current distribution at the top and bottom surface supports the absorption mechanism at the resonance frequencies. To verify the simulations, a prototype of absorber is fabricated on FR-4 substrate and tested in an anechoic environment.
