Abstract

In this paper, we suggested multiband antenna that can be equipped on a inflatable life-jacket, operating VHF-DSC band(156 MHz), COSPAS-SARSAT band(406 MHz) and GPS band(1,575 MHz) for search and rescue survivors quickly. The GPS band antenna was implemented with a square ring-slot planar antenna, and the COSPAS-SARSAT and VHF-DSC band antenna were implemented meander type dipole antennas. In order to place the antenna on a life-jacket, we installed it on 0.2 mm thickness FR-4 substrate to obtain a flexibility. It appeared that the antenna has -14.6 dB, -30.9 dB, and -18 dB return loss in COSPAS-SARSAT, GPS, and VHF-DSC band, respectively. In addition, its gain has 0.83 dBi, 2.1 dBi in COSPAS-SARSAT and GPS band, respectively.

본 논문에서는 해상 조난 시 조난자의 정확한 위치를 파악하고, 신속한 구조를 위하여 팽창식 구명조끼에 장착이 가능하면서 COSPAS-SARSAT 주파수 대역, GPS 대역과 VHF-DSC 대역에서 동작하는 다중대역 안테나를 제안하였다. GPS 대역의 안테나는 사각형 슬롯 링(square slot-ring) 형태의 평판 안테나로 구현을 하였고, COSPAS-SARSAT 및 VHF-DSC 안테나는 미앤드 구조의 다이폴 안테나로 구현을 하였다. 구명조끼에 장착이 가능하여야 하므로 유연성 확보를 위해 안테나를 0.2 mm 두께의 FR-4 기판 및 선형 도선으로 구현하였다. 제작된 안테나는 COSPAS-SARSAT, GPS, VHF-DSC 대역에서 각각 -14.6 dB, -30.9 dB, -18 dB의 반사손실을 나타내었으며, COSPAS-SARSAT, GPS 대역에서의 이득은 각각 0.83 dBi, 2.1 dBi로 나타났다.
