Abstract :
Micromachined patch antennas at 60 GHz were fabricated on 400 μm silicon wafers. These were fed by a microstrip-to-coplanar transition. Good agreement was found between simulation and fabrication designs´ return loss. The attained bandwidth was ~3 GHz. Surface waves excited in the substrate, diminished radiation. This was observed in the radiation patterns. Even so, a 4.6 dBi gain was achieved. Lastly, different feeding mechanisms are mentioned to avoid poor radiation.
