1. A method, comprising the steps of:
creating a pattern for an array of patch antennas on a first major surface of a glass sheet, the pattern having first regions where the patch antennas are to be formed;
performing an ion exchange reaction so that metal ions diffuse into the first major surface of the glass sheet in the first regions and into a second major surface of the glass sheet opposite to the first major surface; and
exposing the glass sheet to a reducing atmosphere and a temperature of 250° C. to 600° C. to cause the metal ions to precipitate into metal layers in the first regions, wherein the metal layers comprise the patch antennas formed at or below the first major surface and a ground plane formed at or below the second major surface.
