Abstract
In this work, a dual-band microwave absorber is proposed with periodic array of unit cells which has of dual-split ring geometry on the top of a metal-backed dielectric substrate. The dual-split ring resonators on the top plane is electrically excited by co-polarized component of incident EM wave and gives two absorption peaks at Wi-MAX (3.5 GHz) and WLAN (5.8 GHz) band due to two resonance modes. These two-resonance modes are named as mode 1 and mode 2 for low and high frequency peaks, respectively. The surface current distributionson the top and bottom planes arestudied to gain insight of dual mode resonance for dual band absorption of the structure. Some parametric studies are also performed on key design parameters i.e., split gap, stub length and split angle for further analysis of the design. The measured results are verified with the simulated ones to test its performance and found to be similar.
