Abstract

In this paper, we propose a textile metamaterial absorber that using screen printing technology. A unit cell of the proposed absorber is motivated from the commercial Chanel logo for wearable applications. The complex impedance of the designed unit cell is analyzed by full-wave simulation. To verify its performance, the proposed metamaterial absorber is fabricated where the silver conductive ink is screen printed on an ordinary textile. From experimental results, the absorptivity of the proposed absorber is around 93 % at 10.8 GHz under normal incidence.

본 논문에서는 스크린 인쇄 방식으로 제작된 의복용 메타물질 흡수체를 제안한다. 제안된 흡수체의 단위구조의 도체 패턴 모양은 의류 브랜드인 샤넬 로고를 차용하였으며, FEM 방식의 시뮬레이션 툴을 사용하여 성능을 검증하였다. 또한, 성능을 검증하기 위해 일반적인 직물 원단 위에 전도성 잉크를 스크린 프린팅 방식으로 인쇄하여 시제품을 제작한 뒤, 벡터 회로망 분석기와 두 개의 도파관을 이용하여 반사계수를 측정하였다. 그 결과, 제안된 흡수체는 10.8 GHz에서 약 93 %에 가까운 흡수율을 갖는 것을 확인하였다.
