초록

본 논문에서는 종이에 전도성 테이프를 이용하여 만든 웨어러블 안테나를 소개한다. 제안하는 안테나는 A4 복사 용지에 반파장 도체 다이폴 스트립과 기생 도체 스트립으로 구성이 되며, SMA 커넥터를 통해 다이폴의 중앙에 급전되는 구조이다. 제안하는 안테나의 모양은 종이 접기에 따라 모양이 달라지며, 따라서 종이를 접었을 때와 펼쳤을 때 안테나의 방사패턴이 가변된다. 이것은 안테나 방사패턴의 영점(null)에 의해 신호의 수신율이 낮아지는 문제점을 해결할 수 있다. 제안하는 안테나의 반사계수와 방사패턴을 900 MHz에서 시뮬레이션과 실험을 통해 제시하였고, 제안하는 종이 안테나가 900 MHz에서 종이접기 방식에 따라 재구성(reconfigurable) 특성이 있음을 보였다.

A wearable antenna made using conductive tape on paper is presented in this paper. The proposed antenna is composed of a half-wavelength conducting dipole strip and a parasitic conducting strip on the A4 copy paper. The antenna is fed at the center of the dipole strip by an SMA connector. The configuration of the proposed antenna changes according to the origami method. Therefore the radiation patterns of the antenna vary according to whether or not the paper is folded. This approach solves the problem that the reception ratio of the signal decreases because of null points in the antenna radiation pattern. The reflection coefficient and the radiation pattern of the proposed antenna at 900 MHz are evaluated using an EM simulation and measurements. It was shown that the proposed paper antenna has reconfigurable characteristics at 900 MHz when utilizing the origami method.
