1. A single-chip sensor/radio for bidirectional wireless communications, comprising:
- a bulk semiconducting substrate, said substrate providing a bulk resistivity of at least 20 ohm-cm or being a thinned substrate having a thickness of 5 to 50 μ
m,a sensor, at least one integrated antenna, at least one transceiver, baseband circuitry, and at least one filter all integrally formed in or on said substrate,a package fully encapsulating said radio to form a packaged radio, wherein a weight distribution of said packaged radio favors said packaged radio landing face up when dropped in a random orientation,wherein data from said sensor is communicable over the air a distance of at least 40 cm to a remote site at a frequency of from 2 GHz to at least 15 GHz.

Abstract
A true single-chip radio for bidirectional wireless communications includes a bulk substrate, at least one integrated antenna, at least one transceiver, baseband circuitry and at least one filter all integrally formed in or on the substrate. The radio preferably includes a low-loss dielectric propagating layer disposed beneath the substrate to improve antenna gain. The integrated antenna can be an adaptive array for beamforming.
