초록
Design of an all-textile microwave absorber for an indoor radar clear is proposed. The proposed absorber consists of two types of square ring resonator having different size, a backing ground plate, and a felt substrate with 1 mm thickness as textile material. All conductive materials are designed using conductive textiles. Different square ring resonators provide a broad absorption band by two neighboring resonance dips. The simulated results yield two absorptivity peaks greater than 96.7% and the full width at half maximum (FWHM) of 15.7% at 9.5 GHz. Also, the high absorptivity is achieved regardless of polarization angles of EM waves.
