- Abstract
- A wearable metamaterial microwave absorber (WMMA) for indoor radar clear applications is proposed. The proposed WMMA is composed of two square ring resonators with different sizes, a backing ground plane, and a felt substrate with a 1-mm thickness. All conductive materials were fabricated using conductive textiles. The grid array of different square ring resonators provides a broad absorption band due to two neighboring resonance peaks. The measured results exhibit two absorptivity peaks greater than 90% and a full-width at half-maximum of 18.9% at 9.475 GHz. Also, the proposed WMMA has a high absorptivity regardless of the polarization angle of the electromagnetic waves and the deformation effect.
