Antenna design and RF layo ut are critical in a wireless system that transmits and receives electromagnetic radiation in free space. The wireless range that an end-customer gets out of an RF product with a current-limited power source such as a coin-cell battery depends greatly on the antenna design, the enclosure, and a good PCB layout.

Recycling processes must be designed to deal with materials that are potentially quite different from the original base material. The changes brought about by the original processing, environmental exposure, and waste treatment must be understood and remedial steps taken to compensate for deterioration in performance.
