Low cost antenna array fabrication technology

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.

Method for Producing Patterned Structures by Printing a Surfactant Resist on a Substrate for Electrodeposition

Methods for electrodeposition of conductive material on a conductive substrate that contains a pattern of a chemisorbed surfactant formed by a stamp having a patterned surface which is pressed onto the surface of the substrate for printing the substrate. Electrodeposition occurs by immersing the patterned substrate in a plating bath upon application of deposition potential or current to the conductive substrate. In embodiment, the chemisorbed surfactant on the surface of the substrate acts as a positive resist so that electrodeposition occurs on regions of the substrate not covered with surfactant. In another embodiment, electrodeposition occurs preferentially in regions of the substrate covered with the chemisorbed surfactant.
