Oblique Resonances Excited in the Near Field of a Satellite-Borne Electric-Dipole Antenna,
Abstract
Near-field patterns of a short electric-dipole antenna were measured in the magnetospheric plasma by an instrument aboard the polar orbiting satellite OV1-20S. The most common antenna pattern observed at the fixed operating frequency, 300 kHz, was a dominantly biconic pattern with major axis parallel to the geomagnetic field. The measured cone angles are in reasonable agreement with those predicted by warm plasma theory. There was no discernible systematic asymmetry in these angles such as could be attributed to field-aligned currents in the plasma or to the motion of the satellite through it. (Author)
