Abstract
957,998. Waveguide phase - shifters. HUGHES AIRCRAFT CO. May 21, 1962 [Sept. 29, 1961], No. 19479/62. Heading H1W. A microwave phase-shifter comprises a transversely-movable longitudinal array of reactive elements. As shown, the elements consist of conductive cylinders 12 mounted upon a beam 14 which may be cast integrally with the cylinders. The cylinders increase uniformly in height to a maximum at the centre of the array and are spaced apart by a quarter-wavelength at the operating frequency, this spacing being physically less at the centre of the array than at the extremities because of the increase in height of the cylinders. The array is mounted upon conductive or dielectric rods 15, 16 and a lead screw 30 whereby the position of the array may be varied between the centre of rectangular guide 20, where it provides a phase lag, and one of the side walls 21, 22, where it provides a phase lead. In a modification (Fig. 6, not shown), the array is mounted within a circular waveguide. The H 11 mode propagated in the circular guide is orientated to provide an electric field parallel to the axes of the cylinders. The invention may also be applied to elliptical waveguides.
