1. A method for making a non-planar radio frequency (RF) device using a mold having a corresponding non-planar shape including a generally spherical portion, the method comprising the steps of:

  • forming an electrical conductor pattern on a flexible substrate;

    positioning and stretching the flexible substrate onto the mold having the non-planar shape including the generally spherical portion so that the electrical conductor pattern is exposed;

    forming a rigid layer on the flexible substrate so that at least a portion of the exposed electrical conductor pattern will be transferred to the rigid layer upon separation from the flexible substrate; and

    separating the rigid layer from the flexible substrate with at least a portion of the electrical conductor pattern remaining on the rigid layer.
