Abstract

본 논문에서는 WLAN 시스템을 위한 CPW 소형 슬롯 안테나를 제안하였다. 길이가 다른 두 개의 스터브와 접혀진 슬롯을 이용하여 20 × 18 × 1 mm3의 소형의 크기로 2.4 GHz 대역과 5 GHz 대역에서 사용할 수 있는 안테나를 모의 실험을 통해 최적화하여 설계 및 제작 하였다. 제작은 1.0 mm 두께의 FR-4 기판으로 하였으며 이중 대역에서 반사 손실 -10 dB 이하의 측정 결과를 얻어 이중 대역 WLAN 시스템용 안테나로서 사용할 수 있음을 보였고, RFID 시스템에서도 사용이 가능할 것으로 기대된다. In this paper, the compact CPW-fed slot antenna for WLAN applications is proposed. While the proposed antenna with size of only 20 × 18 × 1 mm3 is consisted of double stub and folded slot, the antenna for 2.4 GHz band and 5 GHz band is designed and fabricated with optimized parameters obtained by simulation. Proposed antenna is fabricated with FR-4 substrate to the thickness of 1.0 mm. By obtaining the measured return loss level of < -10 dB at dual-band, we showed that it is operated as antenna for WLAN applications, and then it is also expected to be usable as antenna for RFID.
