Abstract

1,197,613. Phase shifters. INTERNATIONAL STANDARD ELECTRIC CORP. 4 Aug., 1967 [8 Aug., 1966], No. 35859/67. Heading H1W. [Also in Division H4] In a planar aerial array (see Division H4) with frequency and phase variations to effect pencil beam directional variation in respective co-ordinates, the phase variation is effected by varying the cross-sectional dimension of a waveguide. In an embodiment the beam elevation angle is frequency sensitive, the individual radiators, e.g. 108, Fig. 1, are crossed slots in columns and rows, each column receives excitation from spaced points along a waveguide formed into a " serpentine " (to afford adequate frequency scan sensitivity) and the serpentines are stacked horizontally and fed from successive points along a variable width waveguide phase distributer to effect beam direction variation in azimuth. Each serpentine, e.g. 102, engages by pin and hole with an adjacent one. A projection 117 fits into the cavity 105 of an adjacent section and includes choke slots 118, 119. A serpentine is connected to a point on the phase distributer-top outline is 103-via a coaxial coupler 113. Phase changing. Fig. 2. A member 203 varies the width of waveguide 209. Slots 204, 205, 206 eliminate R.F. leakage. Bars, e.g. 220, 222, move member 203 whilst maintaining its parallelism with waveguide opening 209. Blocks 218, 219 provide for making fine adjustment of waveguide width by set screws not shown. R.F. power input is at 210.
