Abstract
An improved millimeter wavelength antenna assembly having an input signal coupler, a dielectric waveguide, and a rotatable drum is disclosed. The input signal coupler reduces VSWR return losses and scattered radiation losses from the drum and matches a feeding waveguides characteristics to the dielectric waveguide. Embodiments of the invention include a reflector and a cylindrical lens to direct and form electromagnetic energy radiated by the antenna assembly.
