The Study of Transmission-Line Transformer of Short-Wave Whip Antennas in The Sea

Abstract

The characteristics of the bandwidth and impedance changes of the antenna are analyzed, and the NiZn ferrite trans-mission-line transformer is applied to the six-meter spiral whip antenna to solve the problem of narrow bandwidth, and the influences of taking the conventional transformation ratio or the unconventional transformation ratio of transmission-line transformer are analyzed, and the influences of the bandwidth and reflection coefficient of the antenna are analyzed, and the suitable transmission-line transformer is determined.
