Radiation Resistance of Thin Antennas of Arbitrary Elevation and Configuration Over Perfectly Conducting Ground

摘要

Dipole segmentation is used to estimate the radiation resistance of thin antennas of arbitrary elevation and configuration over a perfectly conducting ground plane. Sample results include half-wave linear antennas of varying inclination, half-wave spiral type antennas, and a TACAMO configuration. Utility of the method for estimating the radiation resistance of VLF/LF trailing-wire antennas from aircraft depends upon the extent to which the current distribution deviates from a sinusoid. That deviation is due in part to finite wire thickness as well as to the finite conductivity of both wire and ground. The influence of those effects requires further study. (Author)
