220 GHz high spatial resolution detector with above-chip mounted dielectric lens
Electronics Letters(2017)
摘要
A novel and low-cost solution to improve the radiation patterns of the on-chip patch antenna at 220 GHz is proposed. The radiation performances are enhanced by mounting the lens on the patch. The air cavity in the lens not only reduces the focal length, but also provides space for chip integration. The imaging chip and antenna are fabricated and an experimental platform is built. The responsivity ...
