This prototype design shows that a compact, efficient, and affordable wafer level antenna can be realized and processed along with MEMs technology on the same material. This prototype high resistivity Si wafer level antenna at K-band has demonstrated its proof of concept and performance. In addition, HFSS will help evaluate new antenna designs on materials, such as GaAs. A full 3-D simulator will continue to be needed to obtain more accurate solutions. Future work will entail simulating the SMA connector effects and comparing the accuracy of the resulting data.
