Abstract :
Work done severe years ago, which represents a step toward eliminating the necessity for subdividing a phased array aperture into many discrete elements, each with its own phase shifter, is reported on for the first time. A 5-wavelength, X band horn aperture, partially loaded with ferrite material, was designed and fabricated. The resulting antenna replaces at least 10 conventional phase shifter-element units and was successfully controlled by an external magnetic circuit to form sum and difference patterns and to scan the beam.
