Metamaterial absorbers have drawn more notice as a way to protect electronic equipment and physical health from harmful electromagnetic radiation. A metamaterial absorber with high electromagnetic interference (EMI) shielding characteristics using modified orbital shaped resonator has been developed in this article. The modified orbital shape resonator-based unit cell configuration is mounted on a metal-backed FR-4 dielectric substrate. This configuration exhibits a triple band near unity response (6.67 GHz with 99.48%, 8.29 GHz with 99.82% and 10.08 GHz with 99.76% absorption) and excellent EMI shielding performance (above 50 dB) in C and X-band for transverse-electric (TE) mode. It also exhibits significant absorption scenario for polarization and oblique incident angle up to 750. The surface current with electromagnetic field analysis are used to investigate the absorption process. A parametric study has been done to achieve triple absorption peaks. The proposed modified orbital shape resonator-based absorber structure is expected to be beneficial for EMI shielding applications.
