ABSTRACT:
A phase scan antenna array for planar radar scanning in a single plane with pencil-shaped beam is provided comprising a plurality of ferrite rod line source antennas. Each rod antenna has a plurality of beam-emitting slots spaced along one side thereof and is end fed in phase with the other antennas from a single hollow metallic waveguide by means of coupling slots in the waveguide which are spaced apart one wavelength of the radar frequency. The rods are mounted in a two-dimensional columnar array with the beam-emitting slots of each rod aligned in rows with the corresponding slots of the other rods by a mounting member having a plurality of mutually-parallel slots in which the rods are disposed. The walls of the mounting member slots suppress Faraday rotation of the waves in the rods and the bottom of the slots enhance the single beam emitted from the face of the array. The array rods are simultaneously magnetically biased by a plurality of serially-interconnected biasing coils which are helically wound around the mounting member and disposed between the rows of beam-emitting rod slots.
