This disclosure describes substrate(s) formed with a three-dimensional (3D) feature thereon, and method(s) of printing the same. One method includes identifying a plurality of locations on a substrate surface where the three-dimensional feature will be formed, determining a height value of the three-dimensional feature at each location, assigning a grayscale value to each location based on the height value, and applying ink to the substrate surface at each location according to the assigned grayscale value.

A method for manufacturing a flex-tolerant three-dimensional printed antenna suitable for use in an electronic device provides a three-dimensional printed antenna with base layer, radiation layer, through holes, and feeder. The radiation layer includes a first radiation region, at least one second radiation region, and a feed end. A region between the first and second radiation regions is defined as a bent region. The radiation layer is formed by a screen-printing plate by a planar printing process. The through holes on the bent region form a line for bending. The feeder is electrically connected to the feed end. The second radiation region is canted from the bending line with respect to the first radiation region to form the three-dimensional printed antenna. The three-dimensional printed antenna and an electronic device are also disclosed.
