Abstract :
In this paper, the latest research results for design and characterization of an 85 GHz fully monolithic integrated schottky rectenna (rectifying antenna) using SiMMWIC (Silicon Monolithic Mm-Wave Integrated Circuits) technology are presented. Under RF excitation in frequency range of 75 ~ 90 GHz a sharp receiving profile at 85 GHz of the designed rectenna is clearly characterized. With different bias currents (0.1 μA ~ 0.44 mA) the working point of the embedded schottky diode (cut-off frequency ~ 0.5 THz at 0 V) could be dynamically tuned for the optimal conversion voltage. The corresponding tuning range of the conversion voltage could be varied from 1 mV to 17 mV at 85 GHz.
