This paper presents a CPW-fed aperture-coupled micromachined microstrip antenna operating at 94 GHz. The design consists of two stacked silicon substrates: (1) the top 200 μm silicon substrate, which carries the microstrip antenna, is micromachined to improve the radiation performance of the antenna, and (2) the bottom 100 μm silicon substrate, which carries the feed CPW line. The performances of this new antenna are compared to the ones obtained with a microstrip-fed aperture-coupled micromachined microstrip antenna designed by some of the authors and published previously. It is demonstrated that a wider bandwidth and a less sensitive input impedance versus the fabrication process accuracy are obtained with the new design presented in this paper. The measured return loss is -27 dB at 94 GHz with a 10-dB bandwidth greater than 30%. The CPW-fed aperture-coupled micromachined microstrip antenna is an efficient solution to the vertical integration of antenna arrays at millimeter-wave frequencies.
