Abstract :
Necessity of decreasing the size and circuit integration of microwave and millimeter wave components has increased the demand of silicon based technology. This paper presents the design of a 60GHz on-chip antenna based on silicon CMOS technology. A monopole antenna is selected for design because of its wideband characteristics. It exhibits an impedance bandwidth from 45GHz to 70GHz. The size of the proposed antenna structure is 1.953mm × 1.93mm × 0.25mm. A minimum |S11| of -31.56dB is obtained at 58.5GHz and |S11| of -27.77dB obtained at desired 60GHz frequency. A top metal layer M6 of antenna as radiating element and bottom layer M1 to work as ground plane for antenna is grown on silicon substrate and inside SiO2 layer. A 15 μm thin layer of SiO2 is used for isolation. Gain of -4.96dB is achieved at 60GHz and gain of -4.81dB is achieved at 58.5GHz. The simulation of design was done in finite element method (FEM) based electromagnetic solver HFSS v 15.0 software package.
