    Abstract: A radar antenna scan drive employs a planetary type drive. An RF antenna is fixed to rotate with a planet gear while the planet rotates around a sun gear. The swept volume of the RF antenna, as it scans, is shaped to be noncircular by the ratios selected for the planetary drive. The swept volume shape is utilized to package a larger RF aperture antenna in a fixed available space that is not circular.
