Abstract

In this paper, we suggest a flexible multiband antenna which can be equipped on an inflatable life-jacket. The antenna can send distress alert and location data of survivors to assist rescue operation when crew or people are in distress. The antenna operate in three frequency bands such as VHF-DSC band (156MHz), COSPAS-SARSAT band (406MHz) and GPS band (1,575MHz). The GPS band is implemented with a square ring-slot planar antenna, the COSPAS-SARSAT band and the VHF-DSC band antenna is implemented by monopole type. In order to give flexibility of substrate to be equipped on life-jacket, FR4-epoxy substrate of thickness 0.2mm is used to make antenna. The reflection coefficients of the fabricated antenna are -8.8dB, -20.4dB and -10.7dB at each bandwidth like VHF-DSC, COSPAS-SARSAT and GPS band, respectively, when people are wearing life-jacket integrated multiband antenna.

본 논문에서는 어선원 및 일반인들이 해상에서 조난을 당하였을 경우 구조를 위해 조난신호 및 위치정보를 송신할 수 있으면서, 팽창식 구명조끼에 장착이 가능한 유연한 다중대역 안테나를 제안한다. 이 안테나는 VHF-DSC 대역(156MHz), COSPAS-SARSAT 대역(406MHz) 및 GPS대역(1,575MHz) 에서 동작하는 3중대역 안테나이다. GPS대역은 사각형 슬롯 링(square slot-ring) 형태의 평판 구조로 구현하였고, COSPAS-SARSAT 대역과 VHF-DSC 대역은 모노폴 구조로 구현을 하였다. 또한 기판은 구명조끼 장착을 위한 유연성 확보를 위해 0.2mm 두께를 가지는 FR4-epoxy 기판을 사용하였다. 제작된 안테나는 최종적으로 사람이 구명조끼를 장착한 상태에서 VHF-DSC, COSPAS-SARSAT, GPS 대역에서 각각 -8.8dB, -20.4dB, -10.7dB의 반사손실 특성을 나타내었다.
