Abstract

In this paper, we have proposed a tapered slot antenna for IR-UWB communication system suitable of indoor positioning in the building. The designed tapered slot antenna is designed using Ansys Inc. HFSS and its standing wave ratio, return loss, and radiation pattern is analyzed. In 2.36 GHz ~ 5.51 GHz and, the designed antenna shows satisfactory return loss at -10 dB and meets the requirement of $VSWR{\leq}2$. The presented designed showed a higher sensitivity for the end-fire propagation characteristics in a specific direction across all bands of the radiation pattern.

본 논문에서는 IR-UWB 통신 시스템의 테이퍼드 슬롯 안테나를 통해 지상 건물의 실내위치인식이 아닌 해양선박 실내에서의 위치 인식에 적합한 안테나를 제안하였다. 제안한 테이퍼드 슬롯 안테나는 Ansys사의 HFSS를 사용하여 전산모의 하였으며, 주파수 영역에서의 반사손실 및 정재파비, 방사패턴 등을 분석하였다. 분석한 결과 2.36 GHz ~ 5.51 GHz 대역에서 -10 dB 반사손실 및 $VSWR{\leq}2$를 만족하였으며, 방사패턴은 모든 대역에 걸쳐 특정한 방향으로 전파에 대한 감도가 높아지는 end-fire 특성을 보였다.
