Abstract

This paper presents a novel CPW-fed UWB monopole paper antenna made by paper and copper tape. Through the simulation, the optimized antenna design parameters were obtained, and an antenna having an omni-directional radiation pattern and a gain of 2.2 dBi or more in the UWB frequency band of 3.1-10.6 GHz was designed. The antenna was manufactured using general A4 paper and copper tape, and the measurement result satisfies the return loss of -10dB or less in the UWB frequency band and confirm that the return loss characteristic was maintained even when the antenna plane was bent by 3 mm in the longitudinal direction. The proposed antenna is a wearable device that can provide services in the UWB band, and can be manufactured inexpensively by printing it with a conductive print on paper. So it can be used as a wearable antenna for UWB communication in various application fields such as logistics and disposable terminals.

본 논문에서는 종이와 동 테이프로 만든 CPW로 급전되는 UWB 모노폴 종이 안테나를 제안하고자 한다. 시뮬레이션을 통해 최적화된 안테나 설계 파라미터를 구하고, UWB 주파수 대역인 3.1-10.6 GHz에서 전방향성 방사패턴 및 2.2dBi 이상의 이득을 갖는 안테나를 설계하였다. 일반적인 A4용지와 동 테이프를 이용하여 안테나를 제작하고, 측정 결과 UWB 주파수 대역에서 -10 dB 이하의 반사손실을 만족하였고, 안테나 평면이 길이 방향으로 3mm 굽어진 경우에도 반사손실 특성이 유지됨을 확인하였다. 제안된 안테나는 웨어러블 소자로서 UWB 대역의 서비스를 제공할 수 있고, 종이에 전도성 프린트로 인쇄하여 제작하면 저렴하게 제작이 가능하므로, 물류 분야 및 일회용 단말기 등 다양한 응용 분야에서 UWB 통신용 웨어러블 안테나로 활용이 가능할 것으로 사료된다.
