Abstract
Aspects disclosed in the detailed description include an antenna on a device assembly. A device assembly includes a silicon device layer having at least one antenna. The device assembly also includes a polymer substrate that is formed with insulating material that does not interfere with the at least one antenna in the silicon device layer. As a result, it is unnecessary to shield the at least one antenna from the polymer substrate, thus allowing radio frequency (RF) signals radiating from the at least one antenna to pass through the polymer substrate.
