Performance of helicopter mounted hf antennas

摘要

Finite-Difference Time-Domain (FDTD) is proving to be a practical and accurate technique for analyzing and predicting the performance of antennas mounted on complex structures. As part of an effort to develop and validate an FDTD code, the impedance and radiation patterns of helicopter mounted loop antennas are predicted and compared to full-scale and 1:10 scale measurements.
