A RF frontend interface for a 61 GHz radio powered communication tag device with a built-in antenna includes an IC embedded in a silicon die with a top metallization layer and a dielectric resonant body linked to the silicon die. A high impedance antenna with two feed points is embedded into the top metallization layer and a RF rectifier and multiplier circuit connected to the antenna feed is integrated in the silicon die and symmetrically placed between the antenna feed points configured to stabilize the antenna resonant frequency with its inherent capacity against varying surrounding materials and generate a positive and negative DC output supply voltage against a bulk potential of the silicon die for directly operating a digital circuit in FDSOI technology embedded in the silicon die. The resonant body is configured to work as a wavelength translator in between the antenna and free space.
