Abstract :
This paper presents a 60GHz planar on-chip antenna fabricated with a standard 0.18-μm CMOS process. The antenna has a U-shaped radiating patch, which is fed by a 50-Ω coplanar waveguide (CPW). It has a compact size of 1.5mm × 1.5mm × 0.26mm. The simulation work is optimized by using an FEM-based 3-D commercial EM software Ansoft HFSS. Simulated results shows that the on-chip antenna has a good impedance from 55GHz to 64GHz and nearly omni-directional radiation patterns and stable gain are also achieved. Measuring experiment has also been conducted to verify the antenna´s performance. Measured results matches well with the simulation, which shows that it has a good impedance matching across 55-64GHz and it can be integrated in CMOS circuits for future wireless network.
