Abstract
A wave guide scanner assembly having an oscillating support for a scanning antenna which is driven by an assembly having no contacting components. The scanner assembly is particularly useful for motor vehicular collision warning systems. The drive assembly for the oscillating support includes a coil and magnet for driving the support when current is applied thereby resulting in translational movement of the magnet and oscillating movement of the support. A spring flexure assembly is connected to the support for providing controlled harmonic oscillation to the support and antenna.
