Abstract

959,004. Aerials. BENDIX CORPORATION. Dec. 19, 1962 [Dec. 29, 1961], No.47963/62. Heading H4A. A slotted waveguide aerial array 22 is supported by a unitary structure 30 of extruded aluminium or magnesium alloy having a length at least as great as the length of the waveguide 22 and including a pair of flared walls 51, 52 (thus limiting the vertical radiation pattern (Fig. 5, not shown)), and a pair of inwardly-projecting portions 31, 32, the edges 40, 41 of which together with the waveguide 22 define recesses 46, 50 having a depth substantially equal to an odd multiple of quarter wavelengths of the main operating frequency, thus suppressing unwanted vertically polarized radiation. The flared sides 51, 52 terminate in a fibre-glass radome 23 (Fig. 3, not shown), which includes de-icing conductors, which also act to suppress vertically polarized radiation; the inner surfaces of the planer wall portions 53, 54 of the radome 23 are metallized to extend the horn 51, 52. The whole assembly is rotatably mounted (Fig. 1, not shown), and is employed as a ship-borne radar scanner. Several arrays may be stacked one on the other.
