ABSTRACT:
Methods are provided for producing large volumes of small antenna arrays. In one embodiment, the method comprises the steps of creating an antenna array pattern as a computer file, printing the created pattern onto the surface of a suitable transfer paper, placing the printed image surface in contact with the surface of a material to be etched, and transferring the printed image to the surface of the material to be etched. The transfer can be effected by any combination of chemicals, heat, and/or pressure. After transfer of the printed image, the transfer paper is removed. The step of removing the transfer paper optionally includes wetting the transfer paper in a manner that dissolves the transfer paper leaving the printed antenna pattern on the surface of the material to be etched. The method further includes the step of etching the non-printed portions of the material, preferably by chemical etching, and removing the printed pattern from the surface of the material to yield an antenna array comprising a non-etched portion of the substrate surface. Arrays, and substrates having an etch-resistant mask for making the arrays, are also provided.
