Abstract: A manufacturing method of an antenna structure includes the following steps: producing a main body by injection molding of a first plastic, wherein the first plastic is a plating grade plastic; covering the main body by a second plastic to form a covering layer, wherein plating can not be done for the first and second plastics concurrently; removing a pre-determined portion of the covering layer, wherein a patterned layer is defined by the unremoved portion of the covering layer, wherein at least one trench is formed by the exposed portion of the main body and surrounding patterned layer; and plating an antenna material in the trench to form an antenna. Thus, the instant disclosure can reduce the manufacturing cost of the antenna structure. Based on the preceding manufacturing method, an antenna structure is also disclosed.

Abstract: An exemplary scrap material transport car (100) includes a chassis (120), a plurality of wheels (110), a plurality of supporting rods (130), a container (140), and a pneumatic piston (160). The chassis includes four connection rods (121, 122, 123 and 124) connected sequentially. The chassis has four corners (125, 126, 127 and 128). The wheels are positioned under the corners, and the supporting rods extend from four corners. The housing includes an opening (141), and two pivoting joints. Two of the supporting rods extending from two corners are connected with one of the pivoting joints, and another two supporting rods extending from the other corners are connected with the other one of the pivoting joints. The housing pivots along a pivot axis between the two pivoting joints. The pneumatic piston connects between the connection rod and the bottom surface of the container.
