About the Edition

This study examines the performance of a communications antenna at various locations on an unmanned helicopter. The suitability of a location is determined by the quality of the antenna pattern, primarily field of view, which is defined as the range of angles over which the antenna gain is constant enough and/or sufficient enough to permit signal reception regardless of the direction of flight. The antenna performance when installed on the helicopter was simulated using the method of moments code PATCH and physical optics code APATCH. The simulated pattern data for the installed antenna was compared to that of the free standing antenna, which is used as a baseline from which to determine the effects of the antenna placement on signal reception. Antennas examined included: (1) a short monopole, and (2) a hemispherical pattern similar to the pattern of commercially available wideband annular slot antennas. The frequency range of interest is from 100 MHz to 1200 MHz.
