    Abstract

    The W-band signal near the antenna surface is detected using a THz probing system, by assuming near/far electric field distribution measurement on a phased array antenna coupled to an RoF radar system. By using 10 GHz + 12.5 kHz optical sampling pulse with a ZnTe EO probing head, the 80-GHz signal generated by a UTC-PD could be successfully detected as a down-converted signal of 100 kHz. It suggests a potential to measure the electric field distributions of 1-D/2-D patch antenna arrays, used in advanced RoF systems.
