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.

Antenna scanner

A flexible wave guide joint is located between a transceiver and oscillating antenna in a vehicular collision warning system. The flexible joint includes a multiple portion wave guide feed. One portion of the wave guide feed is fixed in position and coupled to the transceiver while another portion of the wave guide feed is coupled to the moving antenna. The wave guide feed portions are separated by an air gap to permit oscillation of the antenna relative to the transceiver.
