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… Show more
