Abstract
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.
