Abstract
A microwave reflector antenna for use on an aircraft. The microwave reflector antenna has a stationary plate that is attached to and stationary relative to the aircraft. A rotary plate rotates relative to the stationary plate about an azimuth axis. A rotary joint is attached to the rotary plate and has an axis of rotation that is aligned with the azimuth axis. A reflector is attached to the rotary plate adjacent the rotary joint so that the azimuth axis does not intersect the reflector. Individual ball bearings are positioned between the rotary plate and the stationary plate to allow the rotary plate to rotate about the azimuth axis. The stationary plate has gear teeth positioned along a peripheral side wall of the stationary plate. An azimuth motor is attached to the rotary plate and engaged with the gear teeth to selectively rotate the rotary plate about the azimuth axis.
