On-chip antennas are used in a fully integrated phased-array receiver at 77GHz. The complete down-conversion, power-combining, and phase-generation functions are integrated in silicon with no external mm-wave electrical connections. Each of the 4 receiver elements has 41dB of gain with a NF of 8dB with a system BW of 3GHz.
