| dc.description.abstract | In modern society, a transportation of goods throughout shipping becomes vastly significant. Despite its importance, an accident happens frequently at sea. When the accident occurs, the most important factor is a rescue of survivors. VHF-DSC, COSPAS-SARSAT and GPS are typical systems to save survivors quickly. In this paper, it was designed an antenna that can be equipped on a lifejacket, operating VHF-DSC band (156MHz), COSPAS-SARSAT band (406MHz) and GPS band (1,575MHz). To minimize restrictions of user activity, FR-4(0.2mm thickness) was used in the antenna. While designing, considered the case that the antenna is located above the sea level. And compared a measured outcome and a result of simulation and confirmed that the antenna operated range from VHF-DSC, COSPAS-SARSAT band and GPS band. | - |
