Abstract
An electrical structure having a wire conductor secured to a supporting substrate is fabricated by stitching the substrate with a sewing machine using a wire as one sewing filament of the machine. The particular electrical structure described is a parabolic antenna having a wire screen reflector consisting of a plurality of wire screen sections or 'squares' secured in checkerboard fashion to a supporting frame with the edges of adjacent squares in electrical contact. Each square is fabricated by utilizing the wire stitching technique of the invention to lock stitch a supporting substrate in a grid pattern consisting of the stitched wires disposed in intersecting parallel rows and electrically joined to one another at their intersections to form a screen square.
