Design of a reconfigurable 60-GHz on-chip CMOS-SOI pattern-diversity antenna

A radiation pattern switchable parasitic array antenna on CMOS-SOI (Silicon-on-Insulator) technology at 60 GHz is studied. The 3-element reconfigurable array along with the NMOS transistor switches are fabricated on 130-nm CMOS technology occupying a mere 1.2×2.65 mm2 chip size and giving a simulated gain up to 5.5 dBi with beam switching at ±56°. The fully integrated antenna provides a low-cost diversity solution for the emerging gigabytes per second (GBps) short-range communication systems in the 60 GHz band.
