Abstract
A new high performance maritime rescue antenna is presented, including VHF, UHF and GPS bands in buoy miniaturization environment. By using innovative method of coaxial design, each of their desired radiation pattern and return loss are achieved. Specially, two VHF antennas, with 10dB impedance bandwidth of 4% (155-162MHz) and 8% (230-250MHz) respectively, port isolation of 15dBi are carefully designed. Meanwhile, the gain of VHF antennas is greater than 2dBi in elevation plane and the variation less than 1dBi in azimuthal plane. Circularly polarized UHF antenna achieves the wide beamwidth of 120 degrees at 406MHz, under the gain of 4.5dBi in elevation plane and axis ratio less than 3dBi with quadrifilar spiral inverted-F structure and shorted stub. GPS antenna is in the form of microstrip patch, which has good radiation characteristics. All antennas are finally verified by both simulations and measurements, showing their great potential applications in maritime rescue system.
