Aerospace Vehicle Geometry Effects On Omni-Directional Antenna Radiation Patterns By David Farr and Ron Sisco, Haigh-Farr, Inc.
Ground plane geometry plays a major roll in determining antenna radiation pattern characteristics, especially for omni-directional radiators. Utilizing Finite Difference Time Domain (FDTD) techniques, this paper considers and illustrates the effects that vehicle geometry has on radiation pattern characteristics (both amplitude and phase) for omni-spherical and hemi-spherical antennas mounted on cylindrical bodies with parasitic structures.
At this year’s Military Radar Summit we will look to the future of military radar while examining projects aimed at prolonging the lives of current U.S. military radars. Join us for the only exclusive military radar event in the country!
Savant is a sophisticated computational electromagnetics tool that predicts the performance of antennas mounted on electrically large platforms. Supporting both hardware and algorithmic acceleration, Savant can rapidly simulate in-situ antenna performance on platforms spanning hundreds or thousands of wavelengths.
A.H. Systems double ridge guide horns are broadband antennas that offer excellent performance over the frequency range of 170 MHz to 40 GHz. These antennas are suitable for both radiated immunity and emissions testing.
