    Abstract: A latching ferrite phase shifter for microstrip transmission lines compatible with integrated circuits and incorporating two ferrite materials, one of which is sandwiched between the transmission line and a ground plane and the other of which is on the side of the ground plane opposite the transmission line. The ferrite material between the transmission line and the ground plane is designed to control the amount of phase shift produced by the phase shifter; while the other ferrite material on the side of the ground plane opposite the transmission line is isolated from microwave frequencies but forms a magnetic circuit with the first and has a coercive force and saturation magnetization much greater than that of the first to hold it in a magnetized state above its remanent point.

    Abstract: Described is a longitudinally magnetized, latching ferrite reciprocal phase shifter for use in wave guides having a thickness which causes the wave energy to experience a negative phase shift in passing through the ferrite, and wherein the ferrite material itself fills only the center portion of the wave guide and is longitudinally magnetized by means of coil means surrounding one or more U-shaped magnetically permeable members external to the wave guide but forming with the ferrite within the wave guide a toroid-type magnetic circuit.

    Abstract: Described is an electrically steerable tracking antenna feed system employing a pair of ferrite phase shifters, one of which produces positive phase shift and the other of which produces negative phase shift with increasing applied magnetic field. The ferrite phase shifters, arranged in side-by-side relationship in a bifurcated wave guide, are surrounded by a common electromagnet.
