New Scientist | Evolution of the Car: "The entire functions of a radar system have been squeezed on to a single silicon chip about one fifteenth the size of a penny for the first time.

The miniature system has been created by researchers at the California Institute of Technology in Pasadena, US, who managed to fabricate all the sensing and communications components out of silicon. Their chip is capable of transmitting, receiving and directing high frequency microwaves."
