Abstract
A phase scan antenna suitable for millimeter wave radar applications is pided comprising a four-sided ferrite rod having a series of electromagnetic energy emitting slots along one side of the rod. The remaining three rod sides are enclosed by a metal, channel-shaped member which is spaced from the rod by a plastic, channel-shaped substrate member, so that energy emitted from the rod side which is opposite from the slotted rod side will be reflected to pass out the slotted rod side, to thereby enhance the antenna beam produced by the slotted rod side. A magnetic biasing coil having serially-interconnected coil portions is helically wound about the metal channel-shaped member with the coil portions disposed between the slots in the first rod side to cause scanning of the antenna beam. The ferrite rod may be end fed by either dielectric waveguide sections or hollow, metallic waveguide sections.
