A high voltage responsivity detector in G-band is designed in this paper. Different grounding models for the terahertz detector are analyzed and designed. Gold wire grounding design is superior to traditional grounding designs, which reduce the influence caused by the doping concentration, position and thickness error of conductive adhesive. Detectors are based on the Virginia Diodes Inc G-band zero-bias Schottky diode with low zero-bias junction capacitance. The voltage responsivity test result of the gold wire grounding detector is about 1800 mV/mW in 210–220 GHz. The development of the detector provides the device basis for the realization of a terahertz focal plane imaging system.
