Split L-I square shaped compact metamaterial for Cube satellite applications

摘要

This paper introduces a low profile metamaterial absorber designed and developed inspired by transmission line principle with wide bandwidth for Cube satellite applications. Tunable resonators metamaterial with absorbing features are realized by dielectric surface has attracted growing attention. Physical architecture of the resonators capable of modifying electromagnetic features and spectrum operating range variation, which has not been satisfactorily studied. Hence, we propose this metamaterial resonator structure based microwave absorber with tri-band absorption. Patch structure consists of two symmetrical vertical microstrip lines and two drop holes at the edgs to maximize the electromagnetic wave absorption. Measurement and simulation analysis reveals that the proposed absorber have approximately good match since simulated absorption is above 90% (at 10.62 GHz, 11.64 GHz and 12.8 GHz) although the measured level is 80%. The proposed triple band absorber has potential applications in Cube satellite communication system.
