Design and implementation of a W-band on-chip bowtie-shaped slot antenna fabricated in 180-nm BiCMOS process is presented, and its performance and limitations are discussed. This antenna has a measured impedance bandwidth (S11 <; -10 dB) across the W-band frequency range and a very wide gain bandwidth, making it a candidate for wideband applications. The measured gain for this antenna is 0-1 dBi at 94 GHz. This letter also analyzes the influence of the RF probe to the on-chip antenna performance.
