A 60-GHz Millimeter-Wave Triangular Monopole Antenna Fabricated Using 0.18-m m CMOS Technology

This paper presents a 60-GHz millimeter-wave RFIC-on-chip triangular monopole antenna fabricated with TSMC 0.18-mum CMOS process. A planar triangular-monopole structure fed by the CPW microstrip line is adopted to design the on-chip antenna. The measured VSWR is less than two from 50 to 65 GHz. The simulated H-plane radiation pattern is nearly omni-directional, and the simulated antenna efficiency is approximately 12% due to the loss of the CMOS substrate. The measured maximum antenna gain is about -9.4 dB.
