Millimeter-wave photodetection and direct integration with microstrip slot antenna array

摘要

In this paper, we present experimental results on millimeter-wave photodetection for fiber-radio system. The experiment shows about 5dBm millimeter-wave output from the photodetector at 38GHz and 60GHz, respectively, which is close to the required power for direct fed of the indoor millimeter-wave radiation system. To efficiently radiate the obtained millimeter-wave power, a microstrip slot antenna array directly integrated with the photodetector are designed, fabricated on a glass substrate at38GHz and 60GHz. The simulation results for the antenna is also presented.
