Windows with invisible patterned conductive layers

A system such as a vehicle may have windows. A window may have rigid clear layers such as layers of glass or rigid polymer. A polymer layer may be interposed between the rigid clear layers to form a laminated window structure. A conductive layer such as a silver layer or other metal layer in the window may be configured to block infrared light. The conductive layer may be patterned to form signal paths, a radio-transparent region, and other structures in a window. The conductive layer may be formed as a coating on a rigid clear window layer or may be formed on other window structures. The conductive layer may be patterned by removing conductive material from areas of the conductive layer. An insulating layer that visually matches the conductive layer may be formed in these areas without overlapping the conductive area.
