Antennas in silicon integrated circuits
2009
At 24 GHz, communication range of 10 m is possible using on-chip antennas. Antenna efficiency of 25% is achieved by thinning the substrate to ~50 μm. At 5.8 GHz, using a pair of 6-mm long monopoles, communication range of more than 30 m can be achieved. On-chip antennas can be integrated with RF circuits in CMOS for general purpose communication. At frequencies above ~200 GHz, it becomes practical to integrate a patch antenna. A bond wire antenna has efficiency of ~15% at ~60 GHz.
